Abstract
Nowadays, when engineers take their responsibilities to make the process planning of automobile sheet metal, they’ll decide which type of cam used in the manufacture processes. Since there are various types of cams, if engineers can integrate the selecting rule of the proper cam type into the process planning system of the automobile sheet metal, they’ll be able to use computers with the characteristic of rapid computation, to reach the goal of fast process arrangement.
In this research, the computer aided process planning (CAPP) of automobile sheet metal base on the Spring Solid System is used to construct the cam specifications and collision detection, and establish the cam patterns of stamping die for automobile sheet metal. We use the curved surface model of sheet metal as the input, select the proper cam characteristics of feature recognition of sheet metal and examining the feasibility of cam by using collision detection survey, and finally, get the die layout of the process planning for stamping die as the output.
Base on the knowledge-based expert (KBE) system, this paper define the process and cam protocol by string. The process and cam designs are stored in database for reusing the similar design case.
