【摘要】 面向数控车削加工过程研制了一个虚拟数控加工系统。该系统以Windows2000为开发平台,以 Visual　c++6.0为开发工具,基于OpenGL技术实现了数控车削加工过程3维仿真。该系统能 够有效地仿真数控车削过程,具有更接近实际车削加工过程的特点。同时在仿真研究中,分析了加工过程中由切削力导致的加工误差,实现了对虚拟车削工件加工误差的预测。更多还原

【Abstract】 In this paper a virtual NC machining system is proposed based on NC turning machining process. Windows 2000 is used as the developing platform and Visual C++ 6.0 is used as the developing tools. The three-dimensional NC machining process simulation is accom- plished based on OpenGL technology. By using this system the NC machining can be fully and effectively simulated and the simulation is much more accordant to the real machining process. Meanwhile the machining error caused by cutting force during the machining pro- cess is analyzed to realize the prediction of machining error of the virtual machining workpiece.更多还原
