Machining Simulation for Centrifugal Impeller Based on Modelling of Five-Axis Machining Center

Machining simulation is an important procedure to ensure machining safety and efficiency, especially for five-axis machining. The modelling for Fidia HS664RT five-axis machining center is firt established, and then the tool path for five-axis machining of centrifugal impeller is generated based on NX. The machining simulation is then implimented based on Vericut, and finally the actual machining is realized on Fidia HS664RT five-axis machining center. The machining results indicate the validity of the proposed machining simulation method.
