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.
由于磨前齿轮滚刀能够使得被加工齿轮轮齿根部产生一定量根切，所以被广泛用作高精度硬齿面齿轮的粗加工刀具。
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.
应用该方法可以减少粗加工余量，提高粗加工精度和速度，提高了层切法模具零件数控粗加工效率。
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.
提出在开式整体叶盘的粗加工阶段，采用插铣加工代替传统的五轴数控加工点铣和侧铣，实现高效加工。

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.
