Study on Three-dimension Computer Aided Process Planning System

摘要

Aiming at the problem of process data update and working procedure model,the three-dimension CAPP (Computer Aided Process Planning) based on three-dimension CAD (Computer Aided Design) is proposed.The core of the system is the process model that is used to transfer data between CAPP and CAD system.This system can solve the problem of two-dimension CAPP based on parameter feature modeling of three-dimension CAD and has been applied to some aviation enterprises in china.
