Product Background
The basic course of mechanical manufacturing in higher vocational colleges is a compulsory professional basic course for mechanical majors such as mechatronics, mechanical mold design, CNC machining technology and computer-aided manufacturing, covering engineering materials, metal cold and hot processing principles, process regulations and assembly processes. The course involves the teaching content of metal materials, mechanical transmission, engineering mechanics, etc., with many professional theories and strong practicality. Basic, theoretical, engineering and practical are the essential characteristics of the basic course of mechanical manufacturing. Engineering is the main line that runs through the knowledge system of the basic course of mechanical manufacturing and the goal of talent training. The teaching process shows that theoretical explanations and exercises based on textbooks are far from effective, and students do not feel the usefulness of what they have learned, let alone how to apply it. The traditional basic courses of mechanical manufacturing include theoretical courses and practical courses, and it is necessary to set up production practice teaching points in the factory, so that students can experience the methods and processes of parts processing, establish engineering awareness, and cultivate engineering skills.
The basic virtual teaching software for mechanical manufacturing developed by this project is based on virtual reality technology, combined with virtual reality helmets, operators and other hardware, designed for the processing tasks of some parts of mechanical products, and provides teachers and students with training tools for basic virtual teaching of mechanical manufacturing through teaching demonstration, training operation, network evaluation, courseware resources and other functions, which can shorten the training hours, reduce the wear and tear of equipment training and disassembly, reduce the risk of training accidents for students, and improve teaching efficiency; The boring basic theory teaching of mechanical manufacturing is transformed into a vivid virtual teaching, which fully mobilizes the learning enthusiasm of the students to support the operation and training of many people at the same time, avoids the defects of incomplete training equipment, saves equipment investment, and saves training and teaching venues.

l Composition. The software has five modules: ** teaching module, training operation module, teaching resource module, theoretical examination module and practical training examination module. The main content of the software system includes lathe, milling machine, planer, grinding machine, boring machine and drilling machine 6 kinds of process teaching.
l Uses. Lathes, milling machines, planers, grinders, boring machines and drilling machines are commonly used types of machine tools in production and processing, and beginners in related industries often do not know much about the processing technology of these equipment. Mechanical manufacturing basic virtual teaching software for mechanical products related personnel to provide a teaching platform, in a virtual environment, can vividly obtain the relevant knowledge of mechanical manufacturing basic technology, users can be on the teaching software for virtual teaching learning, virtual training hands-on operation, teaching resources browsing and theoretical and virtual training exams.
Drilling and processing training.
l How to use.
1) Stand-alone virtual mode.
2) Stereoscopic display VR glasses virtual ** way.
l Product features.
1) Intuitively learn the disassembly and assembly operation of each mechanical module, and master the essentials of the steps.
2) Independent disassembly, assembly and maintenance exercises, on the basis of the teaching mode, can strengthen the user's understanding of the disassembly, assembly and maintenance of mechanical products.
3) Teaching courseware is updated in real time, and learning can be retrieved at any time.
4) Automatic scoring and automatic registration of test results, so that the assessment can be quantitatively evaluated.
5) The examination environment is similar to the simulated training, the assessment operation can be recorded, and the content can be reproduced.
Features:
The main functions of the basic virtual teaching software for mechanical manufacturing include teaching, training operation, teaching resource library, theoretical examination and practical training examination functions.
l (1) **Teaching function, 3D demonstration of the structure of basic products of mechanical manufacturing.
The basic machining processes such as turning, milling, planing, and grinding involved in the basic course of mechanical manufacturing are taught and demonstrated, and the operation process of the equipment is displayed in a three-dimensional environment. Use the ** button to control the teaching and demonstration process, and output the target object, tools, precautions, etc. of the current disassembly and assembly steps.
*Teaching can default to the predetermined viewpoint or the user can choose their own viewpoint, and the user can freely change the viewpoint position; The interface provides **speed control buttons, and users can change **or pause, **speed**, single-step continuous**, etc. according to their own mastery.
In the teaching process, you can click the "operation method" button on the right side of the interface to explain the "target object", "use tools" and "precautions" in the operation scene, so that users can fully understand the content in the teaching.
l (2) Practical training operation, 3D training of disassembly and assembly of basic product structure of machinery manufacturing.
Through the interactive operation mode of mechanical manufacturing basic course involved in the basic course of turning, milling, planing, grinding and other basic machining processes for practical operation, in the process of operation, the tools can be selected for operation, and the system checks whether the operation process and the use of tools meet the specifications.
In an interactive state, users can use the mouse to click on objects in the 3D scene to assemble. You can click the "Show Operand Button" below the prompt box, and the object to be manipulated will appear flashing red, while the other objects will appear transparent, helping the user to complete the assembly operation smoothly.
If a tool is required for the operation, it is prompted that the assembly operation needs to use the corresponding assembly tool to complete the operation.
l (3) Teaching resource library, 2D courseware for basic products of machinery manufacturing.
It provides courseware corresponding to the basic course of mechanical manufacturing, as well as other resources, and teachers can add and modify the courseware in the software for students to learn and use. You can choose to open and view the selected courseware on the interface.
The editing of teaching resources is mainly edited into word, ppt, pdf and other courseware forms by professional teachers according to the course requirements and combined with their own teaching habits, so as to realize the autonomy and uniqueness of teaching.
l (4) Theory examination function, mechanical manufacturing basic product structure and principle theory examination.
In the ** theory test in the local area network, the test questions are edited by the teacher, randomly selected in the question bank to generate test papers, and the automatic scoring and automatic registration of results in the examination are realized, so that the assessment can be quantitatively evaluated.
Students can use the client to connect to the teacher's machine to take the test independently, automatically upload the test results to the teacher's machine, and the teacher's machine can automatically review and score through the machine, and can save records.
The theoretical test is edited and set by the professional teacher in accordance with his own teaching habits and teaching content, and the editing function of the theoretical test is mainly operated by the professional teacher.
