摘要： The present invention provides a cutting tool which comprises a cutting tool insert with a tip portion of cBN material having a cutting edge formed therein and a base portion forming a sintered composition with the tip portion, and a body portion coupling the cutting tool insert with a shank of the cutting tool, wherein the cutting tool insert has a rake face and a first flank face defining the cutting edge. The rake face has a negative rake angle relative to an axis parallel to a centre axis of the body portion. A second flank face defining a further edge with the first flank face is formed such that the cutting edge and the further edge do not have a common vertex. The second flank face is tilted with respect to an axis parallel to a centre axis of the body portion by an angle greater than 0°.

摘要： In an edge tool having a cutting edge made of a nonmetal inorganic solid-state material with a facet formed on a ridge of the cutting edge, a pre-wearing layer having a thickness of 5 nm or more and having a surface structure formed by a network of recesses and protuberances surrounded by the recesses is formed on a surface of the facet. The average width of the protuberances is 5 nm to 50 nm. A property value of the pre-wearing layer is different from the property value of the inorganic solid-state material underlying the pre-wearing layer, and there is no solid-solid interface between the pre-wearing layer and the inorganic solid-state material.

摘要： A single point turning tool has a tip including a cutting edge with a tip radius and a linear portion added on one side of and slightly behind the point to form a cutting edge with a linear portion and a protruding portion. The protruding extends beyond the plane of the linear portion which, in turn, extends normal to a longitudinal axis on which the tip radius is centered. During manufacture of a piston, the turning tool is positioned with the linear portion aligned generally with the plane of the finished outer surface. The piston is turned while the tool cuts a helical path or turn around the skirt surface by advancing the tool each turn a desired dimension or lead that is greater than the width of the protruding portion but not greater than the combined widths of the linear and protruding portions. The resulting skirt surface is a series of sequentially adjacent turns, each of which includes a shallow valley, preferably with slightly sloping sides, and each turn has a width equal to the width of the protruding portion of the tool and an adjacent flat or linear portion having a width equal to the difference between the lead of the helix and the width of the adjacent valley.

摘要： A cutting tool made of a material having a high red hardness for the continuous machining of metals and having a geometry determined by the change in measurements of a sample of the metal being machined when the sample is externally loaded to failure. The sample is subjected to a tensile load to produce the failure. Elongation and neck down are caused in the failure area according to the ductility of the metal. The effective cutting or rake angle of the cutting tool is established as a function of the elongation and neck down of the sample. The relief angles of the cutting tool geometry are determined to maintain a self-sharpening cutting edge under the abrasive characteristics of the workpiece material and erosion characterisitcs of the cutting tool material for given machining conditions.The effective rake angle of the cutting tool is also established as the minimum angle producing chips of maximum hardness during the machining operation.

摘要： A cutting insert includes a body having an upper face, a lower face, a plurality of planar flank faces joining the upper and lower faces, and a plurality of curved flank faces joining the plurality of flank faces. A T-land is formed at a downward sloping angle with respect to the upper face. A cutting edge is formed at an intersection of a respective flank face and the T-land. A curved cutting edge is formed at an intersection of a respective curved flank face and the T-land. A micro-channel is formed in one of the flank faces, the curved flank faces and the T-land and proximate one of the cutting edge and the curved cutting edge.

摘要： 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.

摘要： The invention provides a novel machining tool suitable for machining, e.g., lathing, of a workpiece made from a difficult-to-machine material such as fully sintered ceramics and quench-hardened high-chromium cast irons. The machining tool has a conically pointed cutting chip of a cemented metal carbide and provided with a round-bottom groove of a 0.2-0.5 mm radius of curvature running with an inclination angle of 15-60null relative to the cutting face of the chip. The invention also provides a machining method for a workpiece of a difficult-to-machine material by using the above-mentioned machining tool, in which ultrasonic vibrations are applied to the tool in the cutting direction so that abrasive wearing of the flank surface can be decreased.
