NX技术在模具型芯加工中的应用

结合典型曲面模具型芯零件,探索了其可变轴联动数控加工程序的一般方法,进行了复杂异形面型芯零件数控加工工艺设计,实现了复杂异形面型芯零件的粗加工、固定轴曲面轮廓半精加工、可变轴曲面轮廓精加工,同时进行了3D仿真验证,通过后处理生成了实际可执行的可变轴数控加工程序,对实际生产具有较强的借鉴意义。

Technology of NX in the Mold Core Processing

This paper takes the typical surface mold core parts to explore the variable axis NC machining program and designs the CNC machining process of the core parts with Complex contoured surface to achieve the roughing,the fixed shaft surface profile semi-finishing,variable axis surface contour finishing and completes 3D simulation at the same time. The actual executable variableaxis CNC machining process is generated by the post-processing,which gives a strong reference to the actual production.
