Supporting System of Integrated Processing for Gear Chamfering Feature Family

A concept of gear chamfering feature family was proposed to solve the problem of processing parameter calcula-tion and information integration for gear chamfering of vehicle synchronizers.Based on the concept,a supporting system of integrated processing was constructed.In the system,a five-layered structure was adopted to separate the management of system flow and information storage.The supporting technology was described from three aspects including calculation flow,interface technology and result reusing.The key technologies,such as general model building,drawing information standardization and case storage,were given.Finally,a calculation example was put forward to verify the feasibility of the system,and the result illustrates that the supporting system of integrated processing for gear chamfering feature family can effectively reduce the complexity of calculation process,enhance the integration character and expansibility,and obviously improve the productivity and machining accuracy.
