摘　　要：在对塑料模具的型芯进行数控铣削编程前,应对其结构进行分析,对实体上的胶位面、分型面、避空位等进行甄别,并对实体进行整理:对于实体上需要用成形刀加工的结构,比如流道,可以用轮廓线代替;对于不需要使用数控铣切削的结构,比如镶件孔、顶针孔等,可以直接删除。再根据实体的结构、工件材质的切削性能,选择合适的刀具,并编写合适的刀路:对于复杂工件的粗加工选择型腔铣,半精加工选择等高切削,对于狭窄位置选择剩余铣,对于曲面,选择平行铣削进行精加工。对于实体上不同结构的曲面、分型面和斜面等,可以合在一起编写粗加工和半精加工刀路,但应尽量分开编写精加工程序。所有程序完成之后,应对刀路进行动画仿真,以检查所编写的刀路是否存在异常情况。Before the CNC milling programming of the core of the plastic mold,its structure should be analyzed,the glue level surface,parting surface,avoiding vacancy on the entity should be identified,and the entity should be sorted out:for the structure that needs to be processed by the forming knife on the entity,such as the flow path,the contour line can be used instead;for structures that do not need to use CNC milling,such as insert holes,top pinholes,etc.,can be directly deleted.Then according to the structure of the entity,the cutting performance of the workpiece material,choose the right tool,and write the right tool path:for the rough machining of complex workpiece choose cavity milling,semi-finishing machining choose equal height cutting,for the narrow position choose residual milling,for the surface,choose parallel milling for finishing.For surfaces,parting surfaces and inclined surfaces of different structures on the entity,rough and semi-finishing tool paths can be written together,but the finishing program should be written separately as far as possible.After all the programs are completed,the tool path should be animated to check whether there are abnormal conditions in the written tool path.
