摘要
插铣法是一种高效实用的切削加工方法,特别适用于难加工材料的深腔或通孔的粗加工和半精加工。在前期研究并发表的关于使用宏程序编程插铣加工矩形和圆形深腔的基础上,针对椭圆形孔的插铣孔中心的定位方法进行研究,并就部分论文将椭圆参数方程的离心角和椭圆图上标注的圆心角相混淆的情况进行了分析,确定出高效正确的椭圆孔插铣粗加工时插铣孔的定位计算方法,同时给出了插铣加工椭圆孔的加工实例和数控宏程序编制工艺。
The plunge milling is an effective and practical machining method, especially suitable for rough- machining and semi-finishing of hardworking material o f deep cavity or through hole. The location method of center of plug hole milling of elliptic cavity hole was researched based on published in the early stage for used macro program programming to milled rectangular and circular cavity, the positioning calculation method of rough-machining of plunge milling for elliptic cavity hole was efficient and correct determined. At the same, the manufacture instance o f plunge milling for elliptic cavity hole and the process planning of NC macro program were provided.
