In recent years, the numerical control majors of secondary vocational schools are more popular. Usually there are a large number of students in a class. It is reasonable and correct to verify the students' writing procedures. It is necessary to run the machine to get the answer. The physical CNC machine tools are very expensive and do not dare to let students Operation, so all inspections on physical machines are not practical. Micro CNC machine tools can solve this problem well and realize the integration of rational and practical teaching. Keywords micro CNC machine tool desktop CNC physical integration Today, widely used in computer, information application and automation, a group of advanced manufacturing industries marked by numerical control application technology has also attracted extensive attention, which has promoted a large demand for CNC technicians in the society, making many vocational schools CNC application technology is highly concerned, and in recent years, the numerical control application technology of various secondary vocational schools is also very popular. However, the large number of classes, expensive equipment and shortage of funds have caused students to get practical training in a timely manner. CNC programming is an important part of the operation of CNC lathes. It is reasonable and correct to verify the students' writing procedures. The operation can get the answer. The physical CNC machine tool is very expensive and does not dare to let the students operate at will. Therefore, it is not practical and unsafe to test all the large machine tools. Micro-CNC tools can solve this problem, which can effectively link theory and practice, and help students improve their sensory perception of CNC machining, stimulate students' initiative and consciousness, and increase hands-on opportunities. To improve the student's proficiency in the operation of CNC machine tools. It turns out that micro CNC machine tools can solve the problems we face very well, and it is a cost-saving, safe and effective teaching mode and teaching method. According to the numerical control programming method and the students' understanding, the following points are compiled: First, dilute the traditional CNC command format, with the process as the entry point teaching. Most of the teachers in secondary vocational schools organize students to learn and understand one by one according to the order of the numerical control system instructions. In the process of teaching, the format of the numerical control system instructions and the meaning of each parameter will be more focused, thus separating from the processing process. Then students will only remember and understand the instruction format and use of the CNC system in order. It will cause: (1) the subject is biased towards the teaching of theory, which makes the theory and practice out of line, and ultimately the effect in the practice link is not good; (2) students think that learning CNC programming is in the "back formula", the interest in learning is not high Feeling boring; (3) The connection between the various knowledge points is not tight enough, and the logic is not strong, which makes the students unable to master and is not conducive to practical application. What we need to do is to change the existing teaching methods, dilute the teaching of the traditional CNC instruction format, and use the process as a starting point to teach. Let specific examples, let students analyze their processes and choose different CNCs. Instructions, and this requires students to understand the process corresponding to each CNC command. The abstract instruction theory learning in the numerical control system and the application of specific practical operations are alternately trained, focusing on the cultivation of students' hands-on ability and professional skills, fully mobilizing and stimulating students' interest in learning, and improving the adaptability of students to learn NC programming. Second, guided by teachers, students as the main body, flexible application of comparative law. Comparative law is the basic method of understanding things. It helps to reveal the interrelationship of things and deepen people's understanding of the nature of things. In addition, the comparison method can also make the boring content lively and interesting, and learn to entertain. In short, aiming at the actual situation of current secondary vocational students, comprehensive teaching is carried out in the way of theoretical teaching and specific practice. Various methods are used to stimulate students' interest in learning, and students' enthusiasm for specific practical operations is used to strengthen students' study of theoretical knowledge. Interspersed with teaching. With the use of the best, the use of micro-numerical imitation machine tools, practice the theory of rational integration, and constantly improve the education and teaching of numerical control, and cultivate the numerical control technical talents who can keep pace with the development of modern manufacturing. references [1] Ye Bosheng, Dai Yongqing.
