Abstract: With the development of modern technology, higher requirements are put forward for training future practitioners of numerical control. In the teaching practice of cultivating numerical control talents, it is found that students have strong hands-on ability and more hands-on opportunities, but their basic knowledge is weak, and their participation and learning enthusiasm in the classroom are not high. The method of action-oriented and education introduced by German vocational education has certain effect on the cultivation of students' comprehensive ability in numerical control course teaching. This paper mainly starts with the problems existing in the current numerical control course teaching practice, analyzes the typical phenomena, and takes "G92 thread cutting cycle instruction programming and machining" as an example to explore the application of action-oriented teaching method in numerical control course teaching.

Key words: Numerical control, Teaching, Action-oriented teaching method
