涡轮叶盘数控加工优化方法的研究与实现

为提高涡轮叶盘的加工效率和质量，提出了涡轮叶盘数控加工工艺方案，在粗加工阶段，采用插铣方法代替传统的点铣加工，分层加工，减小加工变形。采用UGNX进行涡轮叶盘建模，NERC-Max数控编程，VERICUT刀轨仿真。结果表明，采用插铣方法，切削效率高，刀具和叶片未发生干涉，加工阶段划分、刀轨设计合理。提出的涡轮叶盘数控加工工艺方案可行。

Research and Realization of Optimized 5-axis NC Machining Method for Turbine Blade

In order to improve the efficiency and quality of turbine blade milling, a new method of turbine blade NC milling is presented in this paper, plunge milling is a good method, especially for rough milling of blade. Layered milling method can reduce shape distortion in machining. This article provides solid model of blade using UG-NX, and NC programming by NERC-Max, simulating and analyzing by VERICUT, the result indicate that layered milling, optimization tool path and plunge milling can obtain much better quality and efficiency than traditional manufacturing method.
