车铣加工UG-CAM制造技术研究与应用

应用TCL（Tool Command Language）开发了车铣加工中心BUNMOTECS192FT后处理模块，实现了该机床刀具中心点B轴随动的高级功能，利用UG～CAM数控编程技术，使用平头立铣刀，在车铣加工中心进行C、X、y轴联动，完成了零件曲面加工刀轨设计，解决了T型铣刀加工曲面环槽干涉问题，通过将平头立铣刀轴与曲面法线倾斜一定角度，避开平头立铣刀底齿中心切削，达到零件精度要求。

Research and Application of Milling-lathe Machining and UG-CAM Manufacturing Technology

The post processing functional module of the milling-lathe machining center BUNMOTEC S192FT was developed with TCL, the advanced function of the tool center following with the axis B was accomplished. Applying UG-CAM manufacturing technology and using the end milling cutter with the axis C,X,Y linkage machining, the tool paths of the curved sur- face machining were finished, and the interference problem of machining the curved surface with the T milling cutter was solved. By slopping the end milling cutter with a certain angle to the normal line of the curved surface, the tool bottom center cutting was avoided, and the machining precision was achieved.
