| Research Abstract |
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.
