As the key parts in high-end equipments, the variable curvature complex parts is rather difficult to machine due to the adopting of difficult-to-machine material and the characteristics like complex surface, low rigidity, etc. The contradiction between the increasing demand and the low processing efficiency becomes significant, and the high feed speed machining method provides an effective way for processing the variable curvature complex parts with high quality and high efficiency. In view of the big dynamic error which restricts the improvement of machining efficiency in processing of the variable curvature complex parts with high feed speed, it is one of the key technologies to study the technology of dynamic error tracing and compensation, so as to realize the high efficiency machining for such kind of parts. Dominated by the high feed speed machining and based on the deep analysis about geometric characteristics and processing technology of the variable curvature complex parts, the vibration suppression method for variable curvature complex parts in high feed speed machining will be explored and the precise model of irregular machining deformation error based on the dynamic cutting force will be established. Subsequently, it will also be studied that the methods for contour error tracing and precise estimate of the variable curvature complex parts and for dynamic error compensation based on the processing code with multiple error factors coupling, so as to develop the dynamic error compensation simulation system and finally provide new methods and new technologies of dynamic error tracing and compensation in high feed speed processing for the variable curvature complex parts. The study achievements will provide theoretical and technical support for the processing of variable curvature complex parts with high quality and high efficiency, improve the manufacturing ability and level of key parts in high-end equipments and enrich the manufacturing theory for complex parts.
