Graphic determination of geometric angles on metal-cutting tools

Abstract By the mapping method the relevant planes and straight lines of a cutting tool can be mapped on a projection plane, and then all the angles of the cutting tool in both tool-in-hand and tool-in-use systems can be determined by a simple plane geometric procedure. The advantage of this method is that the effects of various parameters concerning the structure, mounting and motion of a cutting tool on its geometric angles can be intuitively shown. This will make it easier to synthesize and optimize these parameters from the point of view of cutting performance. Furthermore, it is possible to use this method for man-machine interaction in CAD and CAM of complicated cutting tools.
