  • Patent number: 6742970
    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 includes a cutting tool substrate with a rake surface and flank surfaces, as well as a notch at the intersection of a pair of adjacent ones of the flank surfaces. The substrate includes opposite flank surfaces that are opposite from the notch and are disposed at a substrate disposition angle with respect to the rake surface of the cutting tool substrate. The cutting tool further includes a cutting blank that is within the notch. The cutting blank has a rake surface and a pair of exposed flank surfaces wherein a cutting edge is at the intersection of the rake surface and the exposed flank surfaces. The exposed flank surfaces of the cutting blank are disposed at a cutting clearance angle with respect to the rake surface of the cutting blank. The cutting clearance angle is not equal to the substrate disposition angle.

  • Patent number: 6344149
    Abstract: A polycrystalline diamond member and a method for making the same. The member includes a backing and a layer of polycrystalline diamond on the backing wherein the layer of polycrystalline diamond has a rake surface and a flank surface. The layer of polycrystalline diamond has an interior region adjacent to the backing and an exterior region adjacent to the interior region wherein the exterior region terminates at the rake surface. The interior region includes interior diamond particles and a catalyst with the interior diamond particles being bridged together so as to form interstices therebetween. The catalyst is at the interstices of the interior diamond particles. The exterior region includes exterior diamond particles bridged together so as to form interstices therebetween with the exterior region being essentially free of the catalyst. A chemical vapor deposition-applied hard material essentially surrounds the exterior diamond particles.

  • Patent number: 6287682
    Abstract: A process for making a diamond-coated tool and the tool made thereby. The process includes a sintering step. In that step, the tool substrate is sintered in an atmosphere and for a time and at a temperature so that superficial, exaggerated grain growth is promoted that imparts a surface roughness which may serve as anchoring sites during a subsequent diamond coating step which is performed by a vapor deposition technique. The diamond-coated tool prepared by the process includes a large grain substrate surface, and an high bond strength between the diamond coating and the substrate surface.

  • Patent number: 6170368
    Abstract: A cutting insert which includes a holder that contains a pocket and a hard insert that has a rake surface. The hard insert is contained within the pocket so as to present a cutting edge. The cutting insert also includes a chipbreaker which comprises a plate with a bottom surface. The chipbreaker is attached to the cutting insert (or optionally to the holder) so that the plate is spaced above the rake surface of the hard insert a first distance forming a conduit for passage of the chips away from the cutting insert. The conduit is defined at least in part by the rake surface of the cutting insert and the bottom surface of the chipbreaker plate.

  • Patent number: 6161990
    Abstract: A cutting insert having a rake surface and a flank surface wherein there is a cutting edge at the intersection of the rake surface and the flank surface. The rake surface exhibits a sufficient degree of surface roughness so as to provide for microscopic chip control. The flank surface exhibits a sufficiently smooth (i.e., a mirror finish) so as to provide for a workpiece surface finish that approaches (or possibly reaches) the theoretical value attributable for the given cutting conditions.

  • Patent number: 6099209
    Abstract: A cutting tool has a compressing segment for imparting a compressive force to produce a non-porous surface layer on a workpiece of porous material. The cutting tool also has a cutting segment to machine the non-porous surface layer for a desired surface finish. Furthermore, a method for machining a workpiece using such a cutting tool may be implemented to produce a non-porous surface layer on a workpiece of porous material and then to produce a desired surface finish.
