Based on the geometric characteristics of the overall impeller,this paper clarifies the five axis NC milling process of the impeller,plans the tool path for the key parts of the overall impeller based on UG NX software,generates the NC program through the post processor,and uses VERICUT software to build a five axis NC milling simulation platform to simulate the actual operation of the impeller machining machine tool,so as to optimize and verify the NC program,check the machine tool collision and other adverse phenomena in detail.The simulation results show that the optimization of machining based on simulation can predict the possible collision phenomenon in advance,help to optimize the milling process and NC program in real time,ensure the safety and reliability of the machine tool,and improve the machining efficiency and level to a great extent.
