machining time

基本解释

Finer feeds produce better surface finish, whereas higher feeds reduce the machining time during which the tool is in direct contact with the workpiece.
进给越小生成的光洁度越好，而在刀具与工件直接接触时进给越大则可以减少机加工时间。
It will save considerable machining time to use more than one tool in one machine to perform several machine operations either in sequence or simultaneously.
在一台机器上使用数种刀具来顺次或同时进行几项机器操作，将节省大量加工时间。
《新英汉大辞典》
