Abstract: The application of CAD/CAM technology in mechanical drawing courses is one of the hot spots in the current education field. The purpose of this paper is to discuss the application research of CAD/CAM integrated technology in mechanical drawing courses, through analyzing the CAD/CAM technology application course standards, clarifying the teaching objectives and contents, and proposing specific teaching methods and steps for the course implementation of CAD/CAM technology application in mechanical drawing courses, in order to ensure that the students can comprehensively master the basic principles of CAD/CAM technology and the operation skills. This paper demonstrates the specific application process and effect of CAD/CAM technology in mechanical drawing courses by teaching case study on solid modeling of base parts. These studies provide an important reference and reference for improving the teaching quality of mechanical drawing courses and students’ practical ability.
