The application of PRO/E in the teaching of mechanical drawing in secondary school

October 13, 2022October 13, 2022 Alexis Curtis

　　With the development of science and technology, the worldwide demand for skilled personnel is increasing, and in recent points, there is a labor shortage of senior skilled workers in China, which also sounds an alarm for our secondary teachers, how to train skilled workers with solid technology and adapt to the present society quickly and well in the context of China’s industrial development has become an important issue.

　　PRO/E Introduction

　　Pro/E is the abbreviation of Pro/ENGINEER, which is a kind of mold design software developed by PTC Parametric Technology Co. It is the most powerful high-end parametric software for industrial design and the most widely used 3D design software in the market.

　　Useful features for mechanical teaching

　　1. Automatic generation of three views

　　PRO/E can use the model to automatically generate the front view, side view, isometric side view, partial detail, section and auxiliary view of the parts and assemblies, through the software intuitive to check whether the answers to the drawing problems done by the students are correct, so as to improve the learning efficiency of students.

　　2. Compatible with AUTOCAD

　　The software supports designers to reuse their existing DWG resources in the 3D design environment and experience the convenience of digital prototyping. It is an unprecedented experience to use the valuable DWG resources originally stored to create 3D part models.

　　Application of PRO/E in the teaching of mechanical drawing

　　1. Use PRO/E to analyze the intersection line and coherence line

　　As a difficult point in mechanical drawing, students often find it difficult to understand the various intersection lines and coherence lines on the three-dimensional surface, and their thinking is confused. The use of PRO/E can significantly improve students’ spatial senses. Firstly, using PRO/E? By using the engineering drawing function of PRO/E, students can visualize the projection of intersecting lines in all directions. The intersection line of two cylinders with different diameters is difficult for students to understand by general teaching methods, but through PRO/E’s diameter drive, the diameter of one cylinder starts from 0 until the size is twice the diameter of the other cylinder, so that students can see the change process of the intersection line very intuitively.

　　2. Use PRO/E to analyze the combination

　　There are often many answers to the question of filling in the missing lines in the drawing according to the known three-dimensional shape of the view. However, students make many mistakes in the process of filling in the lines. Through PRO/E, students’ answers are modeled in three dimensions by the software, and then transformed into a view to determine the right and wrong of the view drawn by the students, which can give full play to the students’ imagination, and can also correct the original errors in spatial imagination.

　　3. Use PRO / E analysis of sectional views

　　It is difficult for students to imagine the internal structure of the part and to understand the meaning of the section view. The various sections shown by PRO/E can be cut in 3D mode as well as in 2D engineering drawings, allowing students to understand the whole part in detail from all angles and providing them with spatial imagination.

　　4. Analysis of assembly drawings using PRO/E

　　The way to draw parts by disassembling the assembly drawing is a difficult teaching point in mechanical drawing, students are often unclear about the specific appearance of the parts, it is easy to see the body parts as a part, but also often a part into several parts, the use of PRO / E assembly function, not only to the assembly of various materials such as metal, wood, plastic, etc., but also to some complex parts of translucent words, so as to distinguish each part location and features. Thus, the location and characteristics of each part can be clearly distinguished.

　　Through practical teaching, it is found that the key and difficult issues such as intersection, coherence, and assemblies, etc., can be vividly and imaginatively shown to students with the help of PRO/E, which simplifies the complexity and makes the difficulty easy, and increases students’ learning enthusiasm and improves their ability to absorb knowledge. The hands-on ability and autonomy of vocational students are fully developed, and the perceptual understanding of the model is strengthened. And through the use of three-dimensional software, students also have a certain knowledge and understanding of three-dimensional software, which also lays the foundation for future learning PRO/E or other three-dimensional software.

　　With the promotion and application of PRO/E software, I believe that computer three-dimensional software-assisted teaching will promote the reform of the teaching form and method of this course of mechanical drawing, truly realize the students as the main body, give full play to the students’ ability of independent learning and exploration, so that our secondary school students in a relaxed and pleasant atmosphere, to lay a good foundation for mechanical knowledge learning.

Analysis of the development status of agricultural machinery and countermeasures

September 26, 2022September 26, 2022 Alexis Curtis

　　1 Development status quo

　　Under the new situation of substantial transfer of rural labor to non-agricultural industries, China’s agricultural machinery industry has seen a large development, but due to the relative lack of national investment in agricultural machinery, the development of agricultural machinery has not yet kept up with or reached the requirements of agricultural mechanization. There are still many problems and contradictions between the development of agricultural mechanization and the current growing demand of the farmers for agricultural machinery, which are manifested in the following aspects.

　　1.1 The equipment level of agricultural machinery can not meet the needs of the whole mechanization

Many farmers in the grain production, corn harvesting and straw picking mechanization operation broken lack of items, in addition in the production of leading agricultural products, such as facilities vegetables, fruit production and pepper production, etc., agricultural machinery equipment is also insufficient, the service project is relatively single, and in rural areas due to the lack of young and strong labor is common, which will also have an impact on the development of agricultural industries with special characteristics.

　　1.2 The degree of organization of agricultural machinery is not compatible with the needs of agricultural development, mainly in terms of scattered operations, small planting scale and high operating costs, as well as insufficient mechanical efficiency.

　　1.3 The infrastructure and equipment of agricultural machinery service system is poor and backward.

It is difficult to adapt and meet the farmers’ demand for agricultural mechanization mainly in information, information technology equipment is relatively backward, and its own development lacks vitality.

　　1.4 The management mode of agricultural machinery is backward and

Unstable team Because of the lack of attention to the job training of agricultural machinery personnel, resulting in the instability of the grassroots agricultural machinery team, most of the township agricultural machinery personnel age structure showing aging, as well as the lower level of knowledge, the resulting composition of the agricultural machinery team for agricultural machinery management and agricultural machinery technology promotion and other work is difficult to carry out normally.

　　2 Agricultural machinery development countermeasures

　　2.1 Increase investment to promote the process of agricultural machinery

(1) to increase investment in agricultural mechanization, financial funds as a guide, we should actively strive to guide farmers and rural collectives to invest, the extensive development of various economic components to invest together, and actively encourage the whole society to invest in agriculture and further development of efficient agriculture.

(2) to strengthen the construction of agricultural mechanization projects, improve the reserve of agricultural mechanization projects, and to multi-channel, multi-channel to get the project, and strive to change the situation of a single channel, project less and lack of projects.

(3) to increase the strength of subsidies for agricultural machinery, as well as agricultural equipment projects and irrigation construction and so on the total amount of special funds for agricultural machinery, especially to improve the implementation of the whole mechanization process, increase the proportion of investment in the lack of broken machinery, and strive to further accelerate the pace of development of the whole mechanization.

(4) to increase investment in field shaping and the construction of machine roads, to improve the environmental conditions of agricultural machinery operations, in order to promote the rapid and healthy development of the cause of agricultural mechanization, while combining with the local reality, the development of local conditions to regulate the measures to strengthen investment in hardware and software, the full mechanization of local crops to carry out a comprehensive operation.

(5) the agricultural machinery service system construction funds to increase investment. To increase investment in information equipment as well as infrastructure. Improve the degree of organization and the implementation of order-based operations. Through the development of large agricultural machinery and professional cooperation of economic organizations, with the form of orders to farmers to implement mechanized full service, and really fundamentally to lift the worries of migrant workers. Efforts to attract migrant workers to voluntarily return to their hometowns to start their own businesses and invest in the development of agricultural machinery cooperative economic organizations to further accelerate the development of agricultural mechanization.

　　2.2 Improve the work of agricultural machinery services to further optimize the environment for the development of agricultural machinery agricultural machinery management departments to promote the implementation and implementation of agricultural machinery law, and to promote the overall administration of agricultural mechanization in accordance with the law, and strive to accelerate the transformation of functions to strengthen the management of innovation

(1) to develop the local economy in accordance with local conditions, innovative new ideas for the development of agricultural machinery. According to the actual situation of local agriculture and rural economic development, make full use of existing conditions, so that selective, focused and gradually move forward, in accordance with the scientific concept of development, the development of agricultural mechanization new ideas, and develop a program to promote the development of local agricultural mechanization, organization and step-by-step implementation, and strive to create a new work situation.

　　(2) to do a good job in the management of agricultural machinery, agricultural machinery procedures for the public, and standardize the work of agricultural machinery license, the management of agricultural machinery business required materials, workflow, work procedures, fees and charges and supervision of telephone and all public and public, at the same time to simplify the procedure, to provide the masses with efficient and fast service.

(3) to increase the supervision, so that agricultural staff to ensure integrity and self-discipline, efficient work.

(4) To strengthen the work of agricultural machinery maintenance services, the organization and establishment of specialized service teams for agricultural machinery maintenance. For the spring plowing and double robbery and other busy season, actively carry out the repair, repair and maintenance of agricultural machinery and other aspects of the work to ensure that agricultural machinery in good technical condition and the benefits of normal play.

(5) effectively implement and enforce the national policies of supporting and benefiting farmers, and advocate and implement the sunshine and transparent policy, and implement the national policies of benefiting farmers truthfully, and take agricultural machinery purchase subsidies as a bridge to really put into practice the issuance of agricultural machinery purchase subsidies, fully mobilize the enthusiasm of farmers to purchase large and medium-sized agricultural machinery, and then promote the pace of development of agricultural mechanization.

　　2.3 Increase training and publicity efforts to improve the quality of agricultural machinery team

To strengthen the business training of grass-roots agricultural machinery technology promotion personnel, tractor drivers and vocational skills training for migrant workers, and make it combined with the training of new agricultural machinery technology, and constantly improve the professional quality of agricultural machinery management and science and technology promotion personnel and the technical level of agricultural machinery maintenance and driving operations and other related personnel, to better accelerate the development of agricultural machinery to lay the foundation for improving the overall quality of agricultural machinery personnel and optimize agricultural machinery Talent structure.

September 19, 2022September 19, 2022 Alexis Curtis

1. the importance of e-commerce marketing in coal mine machinery manufacturing enterprises

　　1.1 Correct attitude, enhance the responsibility of marketing work

　　Liberating the mind and correcting the attitude is the first thing that marketers should pay attention to in their work. General marketing management, many of the problems are due to the lack of responsibility of the marketing staff and no correct attitude, only the importance of e-commerce marketing has a correct understanding of the marketing work to give sufficient affirmation to ensure a positive mindset to face the design.

　　1.2 Skills training, improve the overall marketing management level

　　Restricted by the economic factors of coal mine machinery manufacturing enterprises, in many coal mine machinery manufacturing enterprises, most of the marketing staff is difficult to access higher level accounting skills training, which makes the marketing management level of coal mine machinery manufacturing enterprises always stop at a lower management level, which brings many problems to the management mode of coal mine machinery manufacturing enterprises in the new era to keep pace with the times.

　　1.3 Strengthen enterprise hardware management, optimize marketing efficiency

　　In the coal mine e-commerce marketing management, all relevant units should pay attention to the management of enterprise internal hardware and equipment to ensure that in the process of marketing work each marketing equipment can provide the required specifications and procedures in a timely and accurate manner, which not only effectively ensures the quality of accounting management of coal mine machinery manufacturing enterprises, but also to avoid bringing huge economic losses to society as far as possible.

　　1.4 Adapt the application of marketing and customer relationship management

　　At this stage, the marketing work of China’s coal mine machinery manufacturing enterprises has reached an advanced international level, which provides the basic conditions for the comprehensive development of coal mine marketing information systems. The information construction of China’s coal mine marketing has basically completed the construction of the production system, and today, TMIS, TDCS and other systems have a mature level of internationalization, and with the rapid development of the world’s Internet technology, which provides very strong support for the current strategic decision-making and marketing of coal accounting work.

　　2. The main strategies for marketing development of Chinese coal machinery manufacturing enterprises

　　A noteworthy phenomenon for Chinese coal mining machinery manufacturing enterprises is that the pace of development of foreign companies in China is accelerating. In the face of increasing market competition, coal mine machinery manufacturing enterprises want to achieve better survival and greater development in the new situation, it is necessary to accelerate the development of modern information technology, through the implementation of e-commerce and other means to improve the business management capabilities of enterprises to enhance the ability to adapt to the market and participate in the competition is an important way out. For China’s e-commerce model, we specifically put forward the following strategies that can be taken.

　　2.1 Construction of enterprise performance appraisal system with balanced scorecard

　　As the balanced scorecard has the characteristics of strategy as the core, process management and goal management, financial and non-financial indicators coexist, and short-term and long-term goals are balanced. Therefore, the balanced scorecard can be used for enterprises in different life cycle stages, but the implementation focus is closely related to the life cycle stage in which the enterprise is located.

　　2.2 Give full play to the marketing function of the website

　　Standing at the level of marketing, the website can not only serve as the online face of coal enterprises, but also one of the important marketing tools for enterprises. Therefore, after the construction of the website is completed, we should maximize the marketing function of the website as much as possible.

　　2.3 Make full use of information technology to improve business management

　　The development of e-commerce has prompted enterprises to fully realize that: to enhance the competitiveness of enterprises, we must make full use of information technology to improve business management. For coal mining machinery manufacturing enterprises can use electronic commerce for centralized procurement management, which will certainly improve the transparency of the procurement process and reduce procurement costs; the use of unified financial management software, direct control of all income and expenses, which will certainly reduce the business risk and improve economic efficiency. The level of application of information technology in business management activities largely reflects the market adaptability and competitiveness of this enterprise, and should not be taken lightly.

　　2.4 The application of data mining technology in accounting work

　　With the development of computer data mining technology, the application of data mining tools in information systems is becoming more and more widespread, even though there is no shortage of technically mature, but for coal mine manufacturing enterprises accounting, a very professional industry, it is difficult to fully meet all the requirements of the industry.

　　3.? Conclusion

　　Coal as China’s important non-renewable resources, its enterprise marketing management work in China’s position is undoubtedly can not be ignored. Coal mining enterprise marketing work not only helps the choice of enterprise decision-making, and this choice is not set in stone in the marketing process, it can be well according to the internal data of the enterprise at any time to check its applicability and make corresponding adjustments to the enterprise situation or timely replacement. Through which the data model can well implement website construction and maintenance for coal mine enterprise marketing management, the system interface is visualized and operative, which is bound to benefit the technical and economic benefits of China’s coal mine business, and will have very good reference and guidance for coal mine enterprise marketing work.

Exploration and practice of teaching mode based on open type of mechanical engineering practical training in applied undergraduate schools

September 8, 2022September 8, 2022 Alexis Curtis

　　1 Overview

　　In order to make mechanical engineering practical training teaching guaranteed in higher education, it must be backed up by comprehensive ability and high quality engineering technicians, especially in engineering education should occupy a particularly important position. The setting of mechanical engineering practical training teaching system should highlight the characteristics of application-oriented talents cultivation.

In recent years, although the national universities have been reforming and innovating in teaching system, they are still bound by the traditional teaching mode and education concept to a certain extent, which restricts the improvement of practical innovation ability of college students.

Since in teaching, colleges and universities tend to focus on knowledge inculcation for students, while the cultivation of field practice and innovation ability is insufficient, which also leads to the lack of students’ enthusiasm to participate in scientific research activities and practical activities.

　　The open teaching of mechanical engineering practical training in applied undergraduate schools realizes the interaction between scientific research and teaching, promotes the development of student-oriented education concept, and deepens the reform of higher education system. Local ordinary higher education schools, which are in the critical period of development to application-oriented, how to promote and improve the construction of open curriculum system of mechanical engineering practical training, optimize the mode of cultivating application-oriented talents as well as comprehensively improve the quality of students’ innovation and entrepreneurship is an important task for the transformation and development of higher education schools and updating pedagogy at present.

Therefore, it is very necessary to explore the teaching reform based on the open type of mechanical engineering practical training in applied undergraduate schools. This teaching reform aims at cultivating professional core skills and improving comprehensive quality, which is an open innovation and entrepreneurship practical training teaching mode.

　　2 Research on the current situation of mechanical engineering practical training teaching in higher education institutions

　　At present, there are some shortcomings in the teaching concept, teaching system, teaching content and teaching methods of mechanical engineering practical training teaching in higher education institutions in China, which are as follows.

　　2.1 The period of practical training is restricted and the content is not sufficient

　　At present, the main contents of mechanical engineering practical training centers in most colleges and universities are general lathe practical training, planer practical training, milling machine practical training, CNC lathe practical training, CNC milling machine practical training, pincer practical training and so on. According to the teaching schedule, 65 people of mechanical design and manufacturing and its automation majors are counted for example (the duration of practical training is 2 weeks), and its mechanical engineering practical training session is divided all students into two major groups equally, and each group is involved in a larger number of practical training (more than 30 people).

The students in each group had 1 week of practical training, and then rotated until the end of the training. In this way, with a limited number of mechanical engineering practical training teaching equipment and a relatively large number of engineering students; each class takes turns to conduct practical training operations according to the groups, and each group has a short learning operation time at its disposal. All these limit the motivation to carry out innovative teaching in mechanical engineering practical training and demotivate students. In today’s teaching, each work type basically emphasizes the safety operation procedures, followed by the explanation of the basic structure and operation methods of the corresponding equipment, and most of them are taught by a single practical training.

　　2.2 Mechanical engineering practical training teaching does not get enough attention

　　For a long time, many colleges and universities do not know enough about the role of mechanical engineering practical training teaching in talent training, and take mechanical engineering practical training teaching as a supplement and verification of theoretical teaching, mainly in the following aspects: insufficient investment in mechanical engineering practical training teaching funds, mechanical engineering practical training equipment is old and backward, which makes some projects impossible to realize; the status and role of practical training instructors cannot be correctly regarded, which causes the team of practical training instructors The age, education and knowledge structure of practical training instructors are not reasonable.

　　2.3 The teaching mode of mechanical engineering practical training is too single

　　Nowadays, most of the teaching staffs carry out practical teaching in mechanical engineering practical training, ignoring the hands-on ability, and the teaching mode is single. For example, practical training teachers directly explain and then let students carry out practical operations, and this teaching mode is difficult to mobilize students’ enthusiasm and improve their innovation ability.

The time for carrying out mechanical engineering practical training courses is also limited, which only allows students to master the basic operation skills and ignores the cultivation of students’ awareness of mechanical engineering practical training. As a result, students often encounter great problems in the process of practical operation, such as the process analysis of processing, the accuracy of processing, and the efficiency of processing. Therefore, the results of mechanical engineering practical training in school cannot be put into the actual production of enterprises normally, which eventually forms a vicious circle.

　　2.4 The links between the types of mechanical engineering practical training teaching are not closely enough connected

　　Mechanical engineering practical training is mainly divided into turning practical training, milling practical training, planer practical training, clamping practical training, CNC turning practical training, CNC milling practical training, etc. Most colleges and universities set the teaching arrangement of mechanical engineering practical training according to the choice of our students, so students do not know why they learn and what is the use of learning when they are in mechanical engineering practical training.

The connection between the types of work is not close enough, which makes it very difficult for students to understand, which obviously affects students’ ability to establish positive concepts and innovation in mechanical engineering practical training.

　　3 Reform ideas of the open teaching mode of mechanical engineering practical training in undergraduate schools

　　3.1 Reforming the teaching concept and teaching method of mechanical engineering practical training

　　Students are the main body of the whole education, and teachers play the role of actively guiding students to learn. To break through the traditional practical teaching mode, accurately combine the current information technology means, such as virtual simulation software, PPT, etc. for dynamic demonstration of the operation process, emphasize theoretical knowledge, highlight the key points of difficulty and safety hidden points, implement teaching with the integration of theory and practice, and give full play to the guiding role of teachers and the main role of students. 　　

Establishing interest groups, providing mechanical engineering training base with richer teacher resources and equipment conditions for students to manage and teach. In the mechanical engineering practical training to make “interactive” teaching deep in the essence of interaction, such as teacher-student interaction, human-computer interaction way. Teachers also need to form the articulation of traditional teaching and new teaching knowledge structure diversification, students can quickly integrate into the new pedagogy of the link.

　　3.2 Update the teaching content of mechanical engineering practical training

　　Mechanical engineering practical training is an important core part of the practical teaching of technical foundation courses of engineering majors, and as a compulsory course of mechanical related majors, it provides the following “mechanical drawing”, “mechanical principle”, “mechanical surveying and mapping” and “mechanical design”. “”Course design”” “graduation design” and other teaching links laid an important practical foundation for mechanical-related professional students to provide the structure of equipment, the use of tools, machinery manufacturing technology, machinery manufacturing production process The teaching should be aimed at training students with modern science and technology.

　　The teaching should be aimed at cultivating innovative and applied talents with modern science and technology, and at improving students’ competitiveness in the future. It should increase the content of today’s advanced manufacturing technologies and applications, as well as the new materials, technologies and processes applied in machinery manufacturing, to enhance students’ understanding and awareness of these new knowledge. Regularly organize students to read relevant technical literature and assign assignments related to the analysis of machining drawings in order to improve students’ abilities in the corresponding areas. In the usual teaching process, introduce the teaching of CNC automatic machining technology, so that students have a certain degree of familiarity with the equipment and methods of modern manufacturing technology, and to a large extent, master the process knowledge and skilled operation skills of CNC machining equipment.

　　3.3 Strengthen the focus on extra-curricular competitions

　　Carefully organize and encourage students to actively participate in the National University?W student manufacturing and processing vocational skills competition, equipment debugging and maintenance skills competition and other types of competitions and scientific and technological practice activities, and strive to win national and provincial awards. Taking the participation in the competition activities as a grip, we promote the students’ understanding of theoretical knowledge, the refinement of hands-on skills, and the spirit of solidarity and mutual aid. At the same time, through more activities of related competitions, we can compete with other teams to enhance students’ teamwork spirit and sense of fair competition, so as to lay a solid foundation for further study, work and business in the future and achieve the purpose of “promoting learning through competition”.

　　3.4 The faculty needs to be lean and multi-talented

　　The establishment of a teacher team with reasonable education, title and age structure is the basic condition to improve the teaching quality, and a high-quality teacher team is the key to the cultivation of application-oriented high-skilled talents. Figure 1 shows that the number of practical training teachers with less than bachelor’s degree gradually decreases and the number of practical training teachers with bachelor’s degree gradually increases, but there is still a shortage of practical training teachers with bachelor’s degree or above. In order to improve the quality of practical training teaching, it is necessary to improve teachers’ education and cultivate teachers’ “double teacher” quality; to take teaching as the root and stimulate teachers’ teaching enthusiasm; to take scientific research as the traction and keep teachers’ scientific research standard; to take application as the guide and improve teachers’ engineering practice ability.

　　4 Conclusion

　　In the process of cultivating students’ comprehensive engineering practice ability and improving students’ innovation ability, mechanical engineering practical training plays a crucial role, and its teaching reform is the main measure to cultivate innovative and applied talents in higher education. Through the teaching reform and practice of mechanical engineering practical training, and then build a mechanical engineering practical training teaching system that closely integrates theory and practice, and adapts application and innovation cultivation, so that mechanical engineering practical training teaching can play a better role in cultivating students’ comprehensive quality and innovation ability.

In the future teaching research and practice, the course team will encourage students to design their own practical projects, cultivate students’ application ability of analyzing and solving practical problems, innovation and practical ability as well as teamwork spirit, and further explore the application of interactive and open mechanical engineering practical training teaching in the school.

Discussion on the reform of experimental teaching of the course “Fundamentals of Machine Manufacturing Technology

September 2, 2022September 2, 2022 Alexis Curtis

0 Preface

Fundamentals of Mechanical Manufacturing Technology” is a new main technical foundation course recommended by the Steering Committee of Mechanical Engineering in 1998, which is a very strong theoretical and practical course with important engineering application value.

The course is mainly supported by the basic theory and basic knowledge of mechanical process and cutting principle, and the organic combination of machine tools, tools and fixtures, etc. The teaching process of the course must have the corresponding practical teaching link with it, that is, the experimental teaching link. Through experimental teaching sessions, not only can digest and understand the theoretical knowledge learned in the classroom, improve their hands-on ability, and can train students to analyze and solve problems, for further study and graduate from the professional work to lay a solid foundation.

In teaching the “Fundamentals of Mechanical Manufacturing Technology” course, I found the following problems: First, the structure of the tool is abstract, and some of them are complicated.

First, the tool structure abstract, some complex tool structure is difficult for students to understand, this is the general problem of the experiment.

Second, the experimental teaching content is old-fashioned and boring, which does not stimulate the students’ interest in learning.

Third, students’ learning purpose is not clear enough, do not pay attention to the experimental teaching link, some students on the experimental class just to cope with, to get credit;.

Fourth, the experimental apparatus is aging and obsolete. Therefore, it is imperative to carry out teaching reform for the experiment of “Understanding and Measuring Geometric Angles of Tools” in “Fundamentals of Mechanical Manufacturing Technology”. In recent years, based on the analysis of the characteristics of this laboratory course, we have carried out reform and exploration in teaching contents and teaching methods, and applied it to undergraduate laboratory teaching, and achieved good teaching effect.

1 Reform of teaching content

Mechanical manufacturing is a profession with strong engineering and practicality, which emphasizes hands-on ability. The experimental teaching link is the main manifestation of its practicality, and students can give full play to and improve their hands-on ability through this link.

As the experiment class involves more tools, the structure of tools is more complex and abstract, and the experimental class time is limited, how to make students proficient in tool-related knowledge, tool measurement methods and strengthen the cultivation of students’ ability within the limited time has become the key to the reform of this experimental teaching.

Therefore, according to the characteristics of the experiment, combined with the current employment needs of students, the experimental lecture content made a superb selection, not only to ensure that students have a comprehensive understanding of the knife, but also focus on the knowledge that students will use in the future in the actual work.

In the process of teaching, it is crucial to develop a main line of the course and link the knowledge points together with this main line, so that the content of the experimental class becomes well organized and has a strong logic.

The content of this laboratory class is divided into three major parts: (1) the application of spatial stereo model to define the tool angle; (2) the recognition of typical tools and the introduction of angle; (3) the measurement method of turning tool angle and its labeling.

1.1 Application of spatial three-dimensional model

Since the tool angle is a spatial concept, here the spatial three-dimensional model is applied to introduce and explain to students the points, lines and surfaces that define the tool angle. The ‘point’ refers to the tool tip, the ‘line’ refers to the main cutting edge and the secondary cutting edge, and the ‘face’ involves two categories, one is the inherent face of the tool itself, which are the front tool face, the main rear tool face, the secondary back tool face; the other category is the 3 planes that need to be constructed in the tool angle definition, which are the base plane, cutting plane and orthogonal plane.

The tool angle is defined in these three planes for both simple and complex tools. With the help of this model, the angle of a common turning tool can be visualized in front of the students, making the difficult to understand spatial concepts visualized. The application of the model in the laboratory class not only simplifies the problems that are difficult to understand, but also enriches the content of the laboratory class and stimulates the enthusiasm of the students.

1.2 Introduction to typical tools and angles

Machining often requires machining surfaces such as external surfaces, hole machining, flat surfaces and complex surfaces. Depending on the surface to be machined, there are different types of tools. General external surface processing commonly used turning tools, turning tools are divided into: external turning tools, end turning tools, internal hole turning tools, cutting tools, grooving tools, etc.; hole processing to achieve many methods, different processing methods to complete different processes.

Commonly used are: drilling, reaming, reaming, boring and pulling holes, where drilling involves tools with twist drill, center drill, deep hole drill, etc. The reaming drill is similar to the twist drill, with more teeth and no horizontal edge. Reamers are used for reaming, and boring tools are used for boring; the common method for processing flat and complex surfaces is milling, which requires different milling tools for different surfaces. Different tools have their own tool angles, and their corresponding geometric angles can be found according to the definition of tool angles. In the laboratory class, the geometric angles of different tools are explained in relation to the application of commonly used tools.

1.3 Measuring and marking of turning tool angles

The angle of a turning tool is simpler than the angle of other tools, and in this experiment the geometric angle of a turning tool is measured with a universal angle table. Then use the adjustable part of the goniometer to find the position of the measuring plane and the position of each plane (or line) that constitutes the angle to be measured, and the geometric angle of the turning tool can be measured according to the experimental measurement method.

2 Improvement of teaching methods

2.1 Application of multimedia technology

In the past, the traditional teaching methods were mostly teacher-based fill-in-the-blank teaching, which was dull and boring to students and did not stimulate their interest in learning. In view of the characteristics of the experiment: the angle of some tools space three-dimensional is very strong, and these abstract problems only by the teacher to explain, it is difficult for students to digest and understand. The above problem is solved by integrating multimedia technology into the experimental class. The combination of graphics, animation, video and other multimedia together makes the typical tool structure come alive in front of the students, which not only deepens their knowledge and understanding of the tool structure, but also stimulates their interest in learning, making the boring class lively and interesting.

2.2 Interaction between teaching and learning

The traditional teaching method of experimental class is that the teacher guides students step by step according to the experimental steps, and the whole class is carried out according to the rules and regulations planned by the teacher [4-5]. Ultimately, students just follow the teacher’s method to come up with an experimental result, and it is not very clear how and why the experiment is done. It is difficult to give full play to students’ intelligence in this way of teaching and limited in terms of improving their hands-on skills. Based on this, and considering that the experiment is not a safety hazard, we propose an interactive teaching-learning model.

First of all, before doing the experiment, students are assigned to review the experimental content after class, and then the experimental class is first reviewed by the teacher and students on the theoretical knowledge of the laboratory class, while the teacher introduces the structure of the instruments and equipment used in the experiment, working principles and methods of use, this part can be regarded as the experimental “preamble” link, the experimental preparatory work are After completion, students will be divided into two groups, each group of 8 people, in each group elected student representatives to explain the experiment, the rest of the students do it themselves, to achieve the interaction between teaching and learning.

After the experiment was completed, each student who did the experiment was asked to talk about his or her experience and what could be improved in the experiment class, and finally the teacher summarized the class situation. After several rounds of classes, the teaching method has achieved excellent results!

3 Conclusion

After several sessions of experimental teaching practice, we have been exploring the teaching rules of the experimental class “Geometric angle of tool recognition and measurement” in the “Fundamentals of Mechanical Engineering” class, using various teaching concepts and teaching methods, consistently insisting on the organic combination of theory and practice, vigorously stimulating students’ interest in learning, motivating them to learn, and fully broadening their horizons. We have been able to stimulate students’ interest in learning, motivate them to learn, broaden their horizons, give full play to their creativity, greatly improve their hands-on ability and cultivate their sense of innovation. The quality of teaching and the effectiveness of teaching have been greatly improved.

Study on the Implementation of Case Teaching Method in Teaching Mechanical Design Course

August 23, 2022August 23, 2022 Alexis Curtis

1 The necessity of teaching reform of mechanical design course and the establishment of teaching objectives

Mechanical design course is an important professional technical foundation course for mechanical majors, with strong theoretical and high practicality, and plays the role of carrying forward and backward in the whole teaching process. The traditional teaching mode emphasizes the transmission of knowledge without paying attention to the application of knowledge and the cultivation of practical ability, and the drawbacks are becoming more and more obvious.

Therefore, it is imperative to actively study the teaching rules of the curriculum and carry out curriculum reform. Based on the implementation of the national “Excellent Engineer Training Program” [1, 2] and our university’s three educational concepts of “Great Moral Education, Great Engineering, and Great Practice”, the teaching objectives of this course are formulated based on the orientation of our university as a teaching and service university: after studying this course In other words, students are required to have the ability of general mechanical design through the study of this course, to have a certain sense of innovation and innovative design ability, and to be able to decompose the knowledge used in the design and have a deeper understanding and grasp of it.

2 Case teaching method based on teaching objectives

Under the careful planning and guidance of teachers, the case teaching method is a method that uses typical cases to mobilize students to participate in discussions and in-depth analysis and practice, to further improve their ability to identify, analyze and solve a specific engineering problem through independent thinking or collective collaboration, to cultivate students’ consciousness of linking theory to practice, and to cultivate the awareness of innovative thinking, active learning methods, communication skills and cooperation spirit. teaching method.

Therefore, the construction of the teaching content and system of mechanical design must be based on the teaching objectives of the course, based on the teaching of concepts, knowledge and methods, arrange the teaching content around the cultivation of ability, and design and refine the project cases related to the teaching content of the course. Different tasks and cases are proposed for different majors of mechanical class, so that they can be more closely integrated with the professional courses.

For example, for mechanical manufacturing majors, the analysis and design of typical machines, such as internal combustion engines, bullhead planers, belt conveyors, lathes, reducers, etc., are used as tasks throughout the teaching process to complete the overall scheme design, simple mechanical analysis, mechanism analysis and design, parts design and assembly design of products; for electromechanical majors, the analysis and design of automatic production lines and electromechanical-hydraulic integration products are used as typical tasks For electromechanical majors, automatic production line and mechatronic-hydraulic integration product analysis and design are typical tasks; for students’ lack of engineering background, they should pay more attention to concretization and life in the selection of cases in terms of learning and understanding of knowledge points.

3 Research on the implementation of case study teaching method

3.1 Combine with life, production practice and scientific research projects, select mechanical cases

When applying the case study method, students’ learning efficiency will be greatly improved if they are guided to take the initiative to think and explore the problems through appropriate questioning and the extraction of engineering cases that are closely related to life and production.

For example, when explaining the four basic types of threaded connections, the examples demonstrate the structural characteristics and applications of each type of threaded connection, and guide students to compare and find the similarities as attributes of threaded connections, and form a complete understanding of a certain type of machinery with the help of concepts.

When talking about worm gearing, the universal indexing head is used as an engineering example. The handle of the indexing head is connected to a single worm gear, and the spindle is equipped with a 40-tooth worm wheel to form a worm gear mechanism with a transmission ratio of 1:40, i.e. the handle turns one revolution and the spindle turns 1/40th of a revolution. If the workpiece is to be divided into z equal parts on the circumference, each equal part on the workpiece is 1/z circle, set the spindle rotate 1/z circle, the handle should rotate n = 40/z circle. By guiding students to carefully analyze the characteristics of worm drive, inspire students’ thinking to find out the differences and similarities between worm drive and gear drive, so as to establish the essential connection between them.

The ultimate purpose of learning mechanical design is to conduct scientific research and innovation, and the birth of each mechanical system will be accompanied by the conception of mechanical system solutions and the generation of new mechanical structures. In the teaching, we can use creative techniques in combination with our own research, and analyze and explain the birth of new things from the discovery of their shortcomings, which will have twice the effect with half the effort.

For example, combined with their own scientific research, the design of highland gap tobacco topping car and its typical structure case into the classroom teaching. In the introduction to mechanical design chapter, the basic requirements of mechanical design are explained with the design requirements of the high clearance tobacco topping car, and the general procedures of mechanical design are explained with the design process and program selection of the topping car.

In the chapter of belt drive, we show the belt drive structure in the topping suspension of the topping car, see Fig. 1, and ask students the following questions with the practical problems encountered in the development of topping suspension equipment: which type of belt is used in the belt drive? What type of belt drive does it belong to? What are the requirements for the installation and operation of this drive form? The questions not only aroused students’ curiosity and debate, but also set up the divergence point of thinking in the classroom, so that students have the space to fully express their opinions, active classroom teaching atmosphere, and in a subtle way accept the new knowledge.

Not only know the V-belt drive, but also have the most direct understanding of the half-cross drive requirements, indirectly gain practical experience, that is, the belt half-cross drive can not be reversed, should be installed so that the wide symmetry surface of one pulley through the belt winding out point of the other pulley. After such a process, students learn not only mechanical knowledge, but also how to identify problems to be solved and effective ways to conceive solutions to problems.

3.2 Adopt heuristic and interactive teaching mode and organize teaching flexibly

The teacher is the leader of teaching, and the students are the main body of teaching. In classroom teaching, the teacher should establish equal and democratic relationship with students to reach unity in thought, consciousness and action. In the teaching of mechanical design course, teachers follow the premise of students’ cognitive law, through creating a learning environment, taking inspiring questions as a carrier, making full use of the role of inspiration and nudging to arouse students’ interest in discovering and exploring problems, so as to activate students’ thinking, make students enter the mental state of conscious learning, and create an active and orderly classroom atmosphere.

In case teaching, it is important to inculcate scientific thinking, scientific method and engineering consciousness in college students and cultivate their team spirit, communication ability, independent learning ability and innovation spirit. For this purpose, flexible teaching methods must be adopted, combining classroom teaching and student group discussion. Some contents of the mechanical design course are not taught specifically, such as the chapter of keys, pins and keyless connections, the classroom lectures on the types of flat keys, characteristics, applications and design verification methods, the spline connection, pin connection, keyless connection of this part of the content is left to students to learn, and finally the teacher to make appropriate summary.

For example, when talking about rolling bearings, after introducing the types of rolling bearings and life verification calculation with multimedia courseware, questions are raised: How to choose the type and model of bearings in the reducer during the design of belt conveyor system? How to position the bearings? How to prevent the axial runout and the shaft from jamming after heating? How to adjust the bearing clearance? How to install and disassemble the bearings? Through the mechanical design “Design and Analysis of Shaft System Components” laboratory class, students analyze the structure and dimensions of each part of the shaft system, and the suitability of each part of the shaft for mounting, positioning and fixing, etc., and make a written report. Students gain a sense of accomplishment while using their own initiative. And at the appropriate time in the classroom, a mechanical design course assignment is assigned: after studying the course, a simple mechanical product report with a complete design process is submitted. 　　

3.3 Combination of modern education technology and traditional teaching methods, do not rely on multimedia

Multimedia teaching is an important tool of modern education. Through multimedia presentation, it can greatly stimulate students’ learning interest, facilitate the breakthrough of teaching difficulties, improve students’ learning enthusiasm, and thus improve learning efficiency .

For example, to teach the structure of roller chain, first show the roller chain with physical pictures and set questions: What are the main parts of roller chain? How are they connected to each other? At this point, students who have a lot of experience in life and have disassembled and assembled chains will speak actively, but most of them are not very clear about the specific structure of the chain.

At this time, we will demonstrate the formation of chain links in the form of animation: the outer link is formed by the interference between the outer chain plate and the pin, the inner link is formed by the interference between the inner chain plate and the sleeve, and the gap between the inner and outer links forms a link, i.e. the hinge. The animation has a first and second, demonstrating the process of connection formation and assembly, and the parts are color-coded and clear at a glance.

At this time, multimedia plays an incomparable advantage of traditional teaching methods, and because of this, some teachers rely too much on multimedia in teaching, a large amount of information in a short period of time, resulting in students often can not grasp the focus, the main and secondary, the teaching content is forgotten after, the teaching effect is often unsatisfactory.

Therefore, in the process of multimedia courseware design and use should do the following.
(1) to focus on updating cutting-edge information, but also to consider the students’ knowledge reserves and cognitive level.
(2) multimedia courseware should be colorful, not all text, pictures, videos and animations should be used appropriately.
(3) pay attention to the combination of traditional teaching tools such as the board, some formulas for the necessary board derivation, important concepts, conclusions written on the blackboard, as a summary of the role. In addition, the use of multimedia and board books should be used more or less to maximize the impression of students and optimize the teaching effect.

4 Conclusion

Teaching practice shows that the case teaching method has the characteristics of vivid, intuitive, and closely related to the actual situation, etc. In the teaching of mechanical design, as long as the mechanical case is carefully selected, flexible teaching methods and the use of modern media technology can well solve the problems encountered in traditional teaching, can effectively combine classroom teaching, innovative theory and practice, can fully mobilize students’ enthusiasm for learning, improve students’ It can fully mobilize students’ learning enthusiasm, improve students’ practical hands-on ability and exploration, cooperation and innovation ability, and achieve the established teaching objectives of mechanical design course reform.
