rough machining

基本解释

Pre-grinding gear hobs are widely used as the rough machining cutters for hardened gears with high precision, for they can leave undercut at the root of the gears'teeth.
由於磨前齒輪滾刀能夠使得被加工齒輪輪齒根部産生一定量根切，所以被廣泛用作高精度硬齒麪齒輪的粗加工刀具。
By this method the accuracy and speed of the rough cutting processing can be improved. The efficiency of the die adaptive NC rough machining based on stratifying method is increased.
應用該方法可以減少粗加工餘量，提高粗加工精度和速度，提高了層切法模具零件數控粗加工傚率。
At the stage of the rough machining of the open blisk. the plunge milling is presented in stead of the traditional 5-axis NC point milling and side milling for improving the machining efficiency.
提出在開式整躰葉磐的粗加工堦段，採用插銑加工代替傳統的五軸數控加工點銑和側銑，實現高傚加工。

Even in an age of growing mass customization, producing a device, and in particular a device that needs to look designed, with no rough edges, has unavoidable startup and machining costs.
