Thin-walled impellers are widely used in aerospace and other high-end manufacturing industries However, the machining of thin-walled impeller is a difficult problem. In this paper, the simulated NC machining for thin-wall impeller with a wall thickness of 1.8 mm is presented. Firstly, the Three-dimensional model of thin-wall impeller with 18 blades is created in SolidWorks. The multi-axis NC machining processing for impeller includes is divided into four stages: roughing and grooving, finishing blade, finishing hub and finishing fillet. All the tool paths for the above-mentioned processing stages are planned by blade expert module in MasterCAM. The five-axis simulated machining for thin-walled impeller is carried out to detect abnormal phenomena such as tool collision by machine simulation module in MasterCAM. The study can simulate the real processing scene for multi-axis NC machining thin-walled impeller and improve the design of NC processing efficiency.
