Centrifugal Pump Impeller 5-Axis NC Machining Technology

The centrifugal pump is a fluid mechanical,and its application is very extensive,which plays an extremely important role in the life and production.With the continuous development of the various fields,high demand has been increased for centrifugal pump impeller work performance,reliability,and development cycle.Centrifugal pump impeller is a typical complex surface parts because of the complex shape and narrow gap between leaves of the centrifugal pump impeller,so its difficulty to process and machining accuracy is not easy to guarantee.After a study of centrifugal pumps integral impeller,it proposed five-axis machining simulation based on UG6.0,and generated rational tool path after treatment to solve the processing problems of the centrifugal pump impeller,as well as provided a meaningful method for complex surface parts process.
