feed engagement meaning in English

每齿进给量

In this paper , a cutting experiment using metal cutting tools with frictional reducing groove is described . the calculation and analysis of measured cutting force data shows that this kind of cutting tools can reduce the data of cutting force . and according to these , the relations among frictional reducing groove parameters and other parameters such as feed engagement were analyzed . cutting tools with frictional reducing groove have practical value when great cutting depth and feed engagement are needed because the cutting force is reduced obviously . frictional reducing groove has wide prospect in the use of non - regrinding tools
通过采用磨有减摩槽的车刀进行切削实验，将测得的切削力数据计算分析得出磨有减摩槽的刀具可降低切削力的数据，并由此分析减摩槽参数与进给量等参数之间的关系.磨有减摩槽的刀具在大切削深度、大进给量的切削加工方面有明显的降低切削力的效果和实用价值，用于不重磨刀片刀具上具有广阔的前景
