摘要
为减少零部件试切,检验数控工艺合理性,构建了虚拟龙门加工中心。研究了龙门加工中心运动,阐述了侧面铣头运动由旋转中心和换刀点控制,提出了虚拟机床侧面铣削运动构建方法,可实现各角度侧面铣。搭建了虚拟加工环境,通过零件仿真加工,完成了零件顶面及4个侧面的铣削加工,验证了数控代码的正确性,检验了数控工艺合理性,减少了零件试切,缩短了开发周期,仿真结果表明虚拟龙门加工中心的正确性。
In order to reduce the trial cut of parts and verify the rationality of the CNC process,a virtual gantry machining center was built.Studying the movement of the gantry machining center,the side milling head movement is controlled by the rotation center and the tool change point,and the side milling motion method of the virtual machine tool is proposed,which can realize the side milling of each angle.Through the part simulation processing,the milling of the top surface and the four sides of the part was completed,which verified the correctness of the NC code,reduced the trial cutting of the parts,shortened the development cycle,and the simulation results showed the correctness of the virtual gantry machining center.
