英文摘要：

In the paper, integrated NC programing and machining process simulation of impeller parts is discussed. Its functional framework and workflow are presented. Then, the environment of integrated NC programing and machining process simulation is built based on SURFCAM and VERICUT. Finally, it is applied to practical impeller machining and the results show that it can effectively handle complex surface machining.
