Simulation of Mechanical NC Machining Based on CAD/CAM

Abstract

In order to solve the problem that the actual utilization rate of simulation technology in the design of modern industrial parts is not high, the author proposes a simulation system based on machining Computerized Numerical Control (CNC) parts. The system combines the numerical control machine tool simulation analysis software VERICUT with the CAD/CAM software PRO/ENGINEER, and carries out the motion simulation of the complex mechanical system twincylinder engine, and completed the simulation processing of the crankshaft die for typical parts, and verified it with the actual experiment. The result obtained is as follows: After optimization, the whole processing man-hour is reduced by 38.43% compared with the man-hour before optimization. Furthermore, the yield rate is increased by 23% after optimization after optimization. It shows that it is an effective method to use VERICUT system and PRO/ENGINEER to carry out complex mechanical motion simulation motion and numerical control machining simulations to achieve complete simulation from design to machining with reliability.
