Abstract: Innovation and entrepreneurship education aims at cultivating talents with basic entrepreneurial quality and pioneering personality, and carries out the training of innovative thinking and entrepreneurial ability in stages and levels. Driven by the environment of "mass entrepreneurship and innovation", it develops rapidly. Its essence is practical education, which is in line with the characteristics of traditional engineering training practice teaching, which focuses on operation, practice and production. Combined with the characteristics of NC machining engineering training course, this paper discusses how to scientifically integrate the characteristics of innovation and entrepreneurship education. By optimizing the application of traditional NC machining practice, changing teaching objectives and optimizing course design, students are required to think comprehensively from product conception, design, production to market investment, so as to stimulate students' entrepreneurial thinking, achieve the purpose of comprehensively improving students' innovative consciousness and comprehensive ability of engineering practice. It can be used as a reference for the practical teaching reform of engineering training.
