基于UGNX的汽轮机叶片锻模CAM

CAM for Forging Die of Steam Turbine Blade Based on UGNX

针对汽轮机叶片锻模传统加工工艺存在的设计制造手段落后、设计制造周期长、质量差、成本高等问题,本文利用UGNX软件加工模块,进行汽轮机叶片锻模的数控编程、加工模拟以及后置处理。采用鼻型硬质合金刀,以型腔铣、跟随周边(工件)方式进行粗加工;采用硬质合金刀球头刀,以固定铣、区域铣削驱动方式进行精加工。这种设计方法缩短了设计与制造周期,提高了模具质量,经生产实践证明是可行的。

Aiming at the problems in the traditional process of steam turbine blade forging die that the design and manufacturing methods are backward,the design and manufacturing cycle are long,the quality is poor,and the cost is high,this paper introduces the method of using UGNX in turbine blade forging die process NC programming,simulation and postprocessing handle.Using nasal-type carbide knife with milling and follow peripheral(workpiece) mode in roughing and carbide ball-cutter knife with fixed milling,area milling driven mode in finish machining.It is proved by practice that the method is feasible.
