摘　　要：对模具自由曲面数控加工工艺的规划方法进行研究,建立了适于模具自由曲面数控加工的工艺规划。针对某模具的自由曲面,根据工艺规划得到的自由曲面加工工艺参数,在UG NX 8.0中设定各项参数,生成刀具加工路径,进行仿真加工,获得其数控加工代码。实例加工证明,该规划方法使模具加工工艺信息得到了最大程度地有效利用,降低了模具设计的工作量,提高了生产效率,降低了设计成本。The authors of this paper, based on their research into the design methods of mold free-form surface NC machining process, have designed a process suitable for mold free-form surface NC machining. According to the machining process parameters of the free-form surface of the mold used in this experiment, the parameters in UG NX 8.0 are set, the tool machining path is generated and the machining process is simulated. The results shows that this design method makes the maximum use of the mold processing information, reduces the workload of mold design, improves the production efficiency and reduces the design costs.
