Abstract
The present invention relates to cutting tools with cutting inserts and, more particularly, to cutting inserts having adjusted cutting edges. The cutting insert comprises a virtual clearance surface that is one of substantially flat and planar and substantially frustoconical. The virtual clearance surface forms a non-zero angle with a perpendicular to a virtual plane of a top surface of the insert. A first virtual cutting edge is disposed above the virtual clearance surface. All points on the first virtual cutting edge are disposed at the plane of the top surface. An adjusted clearance surface differs from the virtual clearance surface and forms the non-zero angle with the perpendicular to the plane of the top surface. An adjusted cutting edge above the adjusted clearance surface, at least some but fewer than all points on the adjusted cutting edge are disposed at different distances from the plane of the top surface. A profile of the adjusted cutting edge viewed in the direction of the perpendicular to the plane of the top surface corresponds to a profile of the first virtual cutting edge. The present invention also relates to a cutting tool.
