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 twin-cylinder 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.
