Abstract:
A cutting tool for removing material from a workpiece wherein the cutting tool is held in a pocket of a tool holder, the cutting tool comprising:a cutting tool substrate that has a rake substrate surface and a plurality of flank substrate surfaces, the cutting tool substrate contains a notch, the notch is at the intersection of a pair of adjacent flank substrate surfaces, the substrate has an opposite corner defined by the flank substrate surfaces that are opposite from the notch; the adjacent flank substrate surfaces are disposed at a substrate clearance angle with respect to the normal to the rake substrate surface and the opposite flank substrate surfaces are disposed at a substrate disposition angle with respect to the normal to the rake substrate surface, and the opposite flank substrate surfaces contact a portion of the tool holder that at least in part defines the pocket; a cutting blank received within the notch; the cutting blank has a rake blank surface and a pair of flank blank surfaces, a cutting edge is at the intersection of the rake blank surface and the flank blank surfaces; the flank blank surfaces are disposed at a cutting clearance angle with respect to the normal to the rake blank surface, and the substrate clearance angle is equal to the cutting clearance angle; and the cutting clearance angle is not equal to the substrate disposition angle.
