High-speed Machining Technology for Impeller Based on UG NX

介绍了基于UG NX7.0的高速数控编程操作过程。分析了典型叶轮零件的工艺设计流程,主要进行了叶轮零件3轴粗铣加工、5轴半精加工,通过深度轮廓、可变轴轮廓、清角加工等方法对叶轮零件各部分进行精加工,进行了仿真验证,执行了后处理,生成了实际可执行的数控加工程序,实现了基于软件的快速高效编程,较好地保障了叶轮零件加工精度,同时应用数控仿真加工软件进行验证,证实了程序与仿真过程的可靠性,可以直接应用于生产加工,对实际生产具有极强的借鉴意义。

High-speed NC programming process based on UG NX7.0 was introduced. The typical impeller parts technics design process was analyzed, mainly for the impeller parts 3 axis rough milling, 5 axis semi finish milling. Through depth contour, variable contour, clearing corner, finish milling for impeller parts was made, simulation and post processing were implemented, then actual ex- ecutable NC program was generated, so fast and efficient programming based on software was realized. The impeller machining accura- cy is guaranteed. The reliability of the program and simulation were verified through numerical control machining simulation software. The program can be directly applied to production and processing. It provides reference for the actual production.
