常规切削用量的选择方法是通过平时加工的经验积累,或通过查工艺手册的查表法来获得。本文通过对经验切削用量的整理、作图,用查图法来获得切削用量,改进了查表法比较麻烦,且查得的参数点比较少的缺点,为零件在进行机械加工时方便的、大范围获得切削用量提供了一种有用的、切实可行的方法 The choice of conventional cutting method is through the accumulation of normal processing experience, or by looking up the process manual look-up table to get. In this paper, through the experience of cutting the amount of finishing, mapping, using Chachart method to get the amount of cutting, improved look-up table method is too much trouble, and check the parameter points less shortcomings for the parts in the mechanical processing convenient, A wide range of access to cutting provides a useful and practical method
