With the gradual advancement of national economic development and education reform, technology-applied talents have gradually become the needs of China's development and have become an urgent need for enterprises to work. Therefore, the vocational education of higher vocational colleges has become an important source of “high-quality technical skills talents” and “strong support for constructing a reasonable educational structure, promoting the transformation of economic development mode, and alleviating the structural contradictions of employment”. In order to meet the needs of the employing enterprise, the process must be based on factory management and teaching according to the knowledge of the personnel required by the factory. However, traditional cramming exam-oriented education is difficult to adapt to the curiosity and curiosity of students in vocational schools, and it is unable to stimulate the motivation of students' learning. In the teaching, our school stimulates students' interest through the analysis and processing of a typical part's processing technology, inspiring students to use all kinds of knowledge to think about problems, so that students can master CNC machining technology, clamping, tool use, programming, Good results have been achieved in terms of machine tool operation and so on.

The above picture is a topic for students to learn macro programs, and student processing is very interesting.
