ABSTRACT:
A cutting insert for milling cam shafts includes first and second surface interconnected by a third surface, and at least one cutting edge. The cutting edge includes a straight first cutting edge section, a straight second cutting edge section, and a generally convex third cutting edge section, all adjoining one another. The first section extends along the junction between the first and third surfaces. The second section extends along the junction and includes a first end adjoining an end of the first section. The second is inclined at an obtuse angle from one end of the first section in a direction away from the third surface. The third section extends along the junction and adjoins a second end of the second section. The third section is of generally convex shape and extends over an angular range greater than 90°. The first, second and third sections lie in the third surface.
