Study on Machining Strategy and Vericut Simulation of Centrifugal Impeller Based on Hyper Mill

Centrifugal impellers are a centre segment of aircraft engines. The machining nature of the impeller straightforwardly affects its service life and mechanical properties. However, the complexity of the impellor blade surface and the requirement for a high degree of accuracy in the finished product means that the process of manufacture is complicated by the need to afford unimpeded access for the cutting tool. This paper describes research into CNC programming and the use of simulations to control the cutting tools, reducing machining errors due to such factors as distortion, collisions and interference. This is especially important where delicate and intricate machining is required as in the example of centrifugal impellers described in this thesis. Therefore, multi-axis NC machining theory, tool envelope surface theory, error compensation principles, numerical simulation technology, post-processing development for five-axis CNC machine tool of dual turntable, simulation and optimization for NC machining of Centrifugal impeller, planning for machining process of impeller and other technical methods were comprehensively studied
