面向数控加工过程的可重配置虚拟加工方法

结合虚拟制造技术对数控加工仿真系统进行了研究,在分析虚拟制造中数控加工仿真技术的基础上,提出了一种可重配置的虚拟加工方法。这种方法通过建立虚拟的部件及部件关系树,根据所需机床的不同类型,来对数控机床的结构进行不同的配置;其中毛坯模型的建立采用的是voxel模型法。此外,运用C++和OpenGL作为开发工具,实现了对数控加工过程的虚拟仿真(即虚拟制造);同时实际应用表明,在虚拟的加工环境下,机床对数控程序的验证时间大大缩短。

The Re - configurable Virtual Machining Method For CNC Machining Processes

It studies NC simulation system to combine with virtual manufacture technology. Based on the analysis of the key technology related to virtual machining system, it proposes a re-configurable virtual machining method. CNC machines can be configured by virtual parts and its relationship tree. It uses the voxel model to represent the stock. A virtual simulation system of CNC machining process (V-Machine) is developed by C++ and OpenGL. The practical application proves that the prove-out time for machine tools can be reduced dramatically by testing NC programs in this environment.
