ABSTRACT:
According to a first embodiment of the present invention, an insert of a multilateral-shaped configuration comprising a rake face adjoining a major cutting edge has the rake face formed so as to comprise a plurality of laterally disposed rake face elements disposed substantially along the major cutting edge and intersecting with each other. The adjoining laterally disposed rake face elements form a ridge which has a convex cross-section and extends to each corresponding major cutting edge. The laterally disposed rake face elements are formed so that the plane angle of each of the laterally disposed rake face elements of one of the rake faces having one of the major faces adjoining the major cutting edge is different from the corresponding plane angle of the other laterally disposed rake face elements of the rake face. Furthermore, according to a second embodiment of the present invention, an insert has two rake face elements in a cascade which comprise a first rake face element having a 90-degree plane angle and adjoining the major cutting edge, and a second rake face element having a less-than-90-degrees plane angle and adjoining the first rake face element and extending opposite from the major cutting edge. A cutting tool adapted for mounting the insert of the second embodiment is also disclosed as an embodiment of the present invention.
