Exploration and Practice on Course Teaching in Plastic Injection Mold

摘要

Mechanical CAD/CAM technology is an important course for the major of mechanical design and manufacturing, with wide teaching content and discipline span. It is also a comprehensive course with strong theoretical and practical characteristics. In the past teaching process, theoretical teaching was emphasized to despise the software operation. Unpractical teaching content directly results in insufficient ability of practice after learning the course. In order to solve these problems mentioned above, teaching reform measures were put forward, such as optimizing teaching contents, implementing modular teaching, introducing skill-based software and formulating typical work tasks. Combined with the theoretical knowledge, students used the software as a tool to accomplish the 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 the students improve their abilities of applying CAD/CAM software after teaching reform in this course. The practical engineering problems are analyzed more thorough and orderly. Employment quantity and quality of graduates are significantly improved to get more praises from enterprises, achieving remarkable teaching effect.
