谈用三爪卡盘装夹车削钢件时的切削用量

On the Cutting Level When Steel Parts Are Clamped on Three-jaw Chuck

指出根据《金属切削手册》给出的切削用量范围确定切削用量,有可能不适当,特别是在三爪卡盘装夹硬度低的半径小的工件时容易发生这种情况,提出根据工件硬度、夹持长度、三爪的夹持半径等诸因素确定切削用量的方法。

It may be not proper to decide cutting level according to the cutting level range specified in the 'Handbook for Metal Cutting', especially when the cutting parts have small radius and small hardness. This paper puts forward the method to decide the cutting level according to such factors like hardness, clamping length, clamping radius of threejaw chuck, etc.
