摘　　要：针对涡轮增压器中关键零件压缩机叶轮加工难点,从毛坯、机床、刀具和装夹方案等方面展开工艺分析,采用叶片粗加工、轮毂精加工、叶片精加工和圆角精加工等4个加工策略进行刀轨关键参数设置,研究了基于NX和VERICUT的刀轨规划及仿真分析过程。分析结果表明:刀轨规划效果良好,可以获得较优的零件轮廓和较高的表面质量,也能够保证叶轮整体性能要求。研究结果也为现场加工此类零件提供了一定的参考依据。Aiming at the machining difficulties of compressor impeller,the process analysis was carried out from the aspects of blank,machine tool,tool and clamping scheme,etc.,and the key parameters of tool path were set by using four machining strategies.The tool path planning and simulation analysis process based on NX and VERICUT were studied.The results of the analysisshow that the tool path planning effect is good,higher parts profile and surface quality can be obtained,and the overall performance of the impeller can be ensured,which provides a certain reference for the on-site machining of such parts.
