Actively promote the teaching reform of numerical control majors, strive to strengthen the training requirements for the ability of numerical control talents, compile the knowledge structure and teaching plan, and send them to each student when they are new students, so that they can familiarize with and understand the majors they have studied, clear their goals and tasks, and change the past. The teaching plan is only in the minds of the teachers, and the students are completely blind. Because this specialty covers many disciplines and is difficult to teach, it should make full use of advanced teaching methods such as multimedia. The practical teaching system is based on the practical links in the traditional training program, attaching to the theoretical teaching, simply serving the problem of theoretical teaching, increasing the intensity of reform, and establishing a practical teaching system that serves the ability training and organically combines with theoretical teaching. The system includes the following structure. Features: Contains four basic practice types: comprehensive or practical—experiment or training, curriculum design or comprehensive curriculum training, internship and graduation design (professional comprehensive training). Form three basic levels of practice, from point to point, and gradually improve. For the practical aspects of the course, including curriculum experiment and curriculum design; the second is for the practical aspects of the discipline, including technical internship and comprehensive training; the third is for professional practice, including production practice, graduation internship, graduation design and professional comprehensive training. . Provides reliable assurance through three training environments. Complete the course experiment and course design in the laboratory environment; complete the technical internship and subject comprehensive training in the simulated engineering environment; complete the professional comprehensive training of CNC equipment installation, debugging, operation and maintenance in the actual engineering environment. The system closely focuses on the training requirements of different abilities, and separately designs the necessary practical links, so that the training objectives, training routes, training environment and training methods of each part of the practical teaching system are clearly visible, so as to enhance the pertinence and practicality of capacity training. For example, electrical technology course experiment, electrician internship, and comprehensive course training services for electrical technology application ability training; electronic technology course experiment, electronic internship and course comprehensive training services for the cultivation of electronic technology application capabilities. Then integrate the four major capabilities to form the application skills of the tomb foundation technology. Based on this, the professional internship through debugging and maintenance is the main content, forming the debugging and maintenance ability of the students' numerical control equipment; forming the students' ability to use the numerical control system and numerical control equipment through the numerical control system programming training, course design and production internship; On the basis of the ability to debug and repair, combined with the basic technology application ability, through the graduation internship and graduation design to form a comprehensive application of students' numerical control technology.
