Study on Rapid Casting for Complex Parts

摘要：

　　A rapid casting method for complex parts is presented.In this method,casting moulds with complex cavity are manufactured by self-created rapid prototyping approach which called Selected Laser Partitioning for Prototyping.After surface coating treatment for moulds,complex parts are obtained by centrifugal casting.As application cases,metal impeller was casted by this method.A self-developed five-axis coordinate measurement machine was used to process the surface measuring of impeller.The Dimension accuracy grade of impeller is CT-3 and the surface roughness is Ra 6.3μm through making comparisons directly between CAD model and point cloud data of impeller surface.The result shows that this rapid casting method which has the characters of simple technology and low production cost reaches the level of precision casting.
