According to the structure characteristics of an automotive turbocharger impeller,based on the machining process a-nalysis,and taking reasonable measures for the key points and difficulties in the actual processing,a more practical processing program was put forward. With CAM software (UG)platform,the tool path of the impeller was planned,and post-processing program was sim-ulated. Finally,this machining program was verified feasible through practical processing.%根据某涡轮增压器叶轮的结构特点，在分析其加工工艺的基础上，针对实际加工中的重点及难点给出了合理的措施，进而提出一条比较实用的加工方案，凭借CAM软件（UG）平台，对该叶轮的刀路进行规划，并对后置处理后的程序进行仿真。通过实际加工验证了此加工方案具有一定的可行性。
