On VC++ platform, the simulation system of VNC turning process is developed by Pro/TOOLKIT development module of Pro/E, and by integrated the above geometry simulation models of NC lathe and the mathematical models of chip.

• 采用Pro/E中的二次开发模块Pro/TOOLKIT，以VC++6.；0为平台，集成上面所建立数控车床的几何模型和切屑的数学模型，开发了虚拟数控车削过程的仿真系统。
