The actual geometry of the cutting tool involved in machining

Z.Y. Shi and Z.Q. Liu

Abstract: Understanding actual geometry of the cutting tool involved in machining is critical to the investigation of the mechanism of cutting process. According to control pattern of the flank and the insert shape, the cutting tools are classified into four different types in this paper including S- and non-S-shaped tools with cylindrical control and conical control. By establishing all the four kinds of tools’ 3D models, the actual geometry of the cutting tool can be obtained. Research results suggest that the actual geometry involved in machining of the S-shaped inserts whether with cylindrical control or conical control is sphere; non-S-shaped with cylindrical control tools is ellipsoid while non-S-shaped with conical control is paraboloid.
