Abstract
Mechanical CAD/CAM technology is an important course for the mechanical design and manufacturing major. Its scope has a wide teaching content and discipline span, and is regarded a comprehensive course with strong theoretical and practical characteristics. Theoretical teaching was emphasized in the past to undervalue software operation. Unpractical teaching content directly resulted in student’s insufficient practice after the course. Thus, teaching reform measures were proposed, such as optimizing teaching contents, implementing modular teaching, introducing skill-based software, and formulating typical work tasks. Combined with theoretical knowledge, students used the software as a tool to accomplish designated tasks and reach corresponding teaching objectives. Taking mouse punch as an example, MasterCAM software was used to introduce the specific mode of task-oriented teaching in CAD/CAM experiments. Results show that students improve their abilities of applying CAD/CAM software after the course’s teaching reform. Practical engineering problems are analyzed thoroughly and orderly. Employment quantity and quality of graduates are significantly improved to gain praises from enterprises and achieve a remarkable teaching effect.

Summary
With the development of advanced manufacturing technology, CAD/CAM technology has become the core of modern manufacturing technology, which greatly improves the design, manufacturing, and management of enterprises. Mechanical CAD/CAM courses and teaching methods must be reformed to make the teaching process serve the enterprise's requirements for students and to cultivate highly skilled and creative talents. The teachers overemphasize the theoretical knowledge of mechanical CAD/CAM technology, which neglects practical operation. Peng (2009) expounded the teaching reform of a 3D CAD/CAM course based on curriculum setting, teaching mode, and material compilation, which improves 3D modeling and the map recognition abilities of students [5]. The teaching content is optimized to divide the teaching module, which enables students to understand CAD/CAM core knowledge. Mechanical CAD/CAM technology teaching is characterized by extensive teaching content and subject span. The basic idea of the research project reform is described as follows
