Abstract
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.
Highlights
Plastic injection mold design is one of the professional technical courses in Mold design and manufacturing profession and is the key course in mechanical manufacture and automation profession
Existing survey results have shown the separation of current theoretical teaching methods of this course from practical applications in most colleges and universities
Considering this undesirable teaching effect, we can summarize the main problems in the teaching process as follows: 1. The theory course results in cramming education which fails to fully mobilize the learning initiative and enthusiasm of students
Summary
Plastic injection mold design is one of the professional technical courses in Mold design and manufacturing profession and is the key course in mechanical manufacture and automation profession. With its strong comprehensiveness and practicality, plastic injection mold design has become a core subject for cultivating vocational skills of design, production, and management in the mold industry. Existing survey results have shown the separation of current theoretical teaching methods of this course from practical applications in most colleges and universities. Students cannot really understand the teaching content, leading to failure in mold design practice. Considering this undesirable teaching effect, we can summarize the main problems in the teaching process as follows: 1. Students will regard mold design principles and trivial content as difficult and boring. Many knowledge points exist in plastic injection mold design teaching, seeking the relationship between these knowledge points is difficult for students. Only some fragmented knowledge points are accepted without systematization
