CUTTING INSERT WITH ELLIPTICAL CUTTING EDGE

摘要

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 (A1, A2, A3) 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.

1. A cutting insert, comprising:
a front surface, a rear surface opposite the front surface, a first end surface, a second end surface opposite the first end surface, a first side surface, a second side surface opposite the first side surface, a first cutting edge formed at an intersection between the front surface and the first end surface, wherein the front surface is continuously convex and extends entirely between the first and second end surfaces and entirely between the first and second side surfaces, and wherein the first cutting edge is elliptical in shape.
