Abstract
A cutting insert for a cutting tool is described. The cutting insert includes a front surface, a generally planar rear surface opposite the front surface, a generally planar first end surface, a generally planar second end surface opposite the first end surface, a generally planar first side surface, a generally planar second side surface opposite the first side surface. The front surface is continuously convex extending entirely between the first and second surfaces and entirely between the first and second side surfaces. At least one end surface is formed with a clearance angle (A, A, A) to produce a cutting edge that is elliptical in shape having a relatively small depth-of-cut (DOC) to produce an extremely fine finish on a workpiece.
