问题的提出成型车刀一般都是单件或小批量生产。不可能配备大量的专用二类工装,型面的加工基本靠手工操作。这种传统工艺流程有哪些缺点,如何改进,这是我们所要讨论的。成型车刀生产的传统工艺流程以机械加工为主要加工手段。但对于批量小而型面复杂的成型车刀,传统工艺流程的经济效益并不高,因为: The question raised Molding turning tools are generally single or small batch production. Can not be equipped with a large number of special second-class tooling, the basic processing of the surface by manual operation. What are the shortcomings of this traditional process, how to improve, this is what we have to discuss. The traditional production process of forming turning tools takes machining as the main processing method. However, for the small and complex surface forming tools, the economic benefits of the traditional process are not high because:
