Abstract: In order to ensure the process plans are feasible and efficient which are generated by a mold CAPP expert system, the process procedure simulation including geometric simulation and physical simulation is integrated to verify it. According to the simulation results, the process plans are often modified to optimum. Thus the purpose can be realized to improve the first-time-try-mold success ratio. Based on the tool path simulation and verification functional model of UG/CAM, the model reference adaptive control (MARC) method is used to realize the physical simulation function. A system model as an academic solution is designed to improve the mold CAPP expert system.
