Abstract: Engineering training teaching is the practice and innovation of very important teaching link.CAD/CAM and CNC technology are the most dynamic part of modern mechanical industrythe reasonable teaching design(teaching process, teaching process, teaching case), it contains ably computer-aided design and computer-aided manufacturing and integration of CNC machining technology for training, not only let the students to ground of the enterprise, also fully excavate innovative and practical ability. In engineering training teaching, the introduction of CAD/CAM and CNC technology training project, effectively improve the quality of teaching of practice and innovation of school.
