Identification of Domain of Orthogonal Cutting Model in 3-Dimensional Cutting

为了在同时测量切屑流动方向角和由此产生的切削阻力的基础上确定正交切削模型的域，进行了研究。在直刃切削实验中，切屑流动的方向角和合成切削阻力的投射角随刀具倾角成比例地增大。在圆刃口实验中，无论刀具倾角的变化，圆刃口的前一角度增大，后一角度基本保持不变。因此，澄清了正交切削模型的域由合成切削阻力矢量和刀具进给矢量组成。

This study had been carried out in order to identify the domain of orthogonal cutting model based on the simultaneous measurements of the chip flow directional angle and the resultant cutting resistance. In the experiment using a straight cutting edge , the directional angle of chip flow and the projected angle of resultant cutting resistance increase in proportion to the tool inclination angle. In the experiment using a circular cutting edge, the former angle increases and the latter angle keeps nearly constant regardless of the change of the tool inclination angle. Consequently it has been clarified that the domain of the orthogonal cutting model consists of the vector of resultant cutting resistance and the tool feed vector.
