摘要： A cutting insert based on a non-limiting aspect has a first member and a second member joined to the first member. The second member has an upper surface and a side surface adjacent to the upper surface. The upper surface includes a first side, a second side and a corner. The upper surface has a first convex portion extending toward the corner, and a second convex portion extending from the first convex portion toward the first side. The second convex portion has a first end portion and a second end portion located closer to the corner than the first end portion. A first length from the first end to the first side is less than a second length from the second end portion to the first side in a top view.

摘要： A cutting insert may include an upper surface, a side surface, and a cutting edge. The upper surface may include a first breaker portion and a second breaker portion. The first breaker portion may include a first surface inclined downward and a second surface inclined upward. The second breaker portion may be inclined upward as the second breaker portion extends away from the first breaker portion. An inclination angle of the first surface may be constant along the first side portion. A length of the first surface may be greater at a second end portion than at a first end portion. An intersection portion of the first breaker portion and the second breaker portion may be orthogonal to the first side portion, or inclined away from the first corner portion as the intersection portion extends away from the first side portion.

摘要： A cutting insert including a surface involved in cutting, for which a cutting tool material of a hard sintered body is used. A radius of a nose R portion is 0.4 mm or greater and 2.4 mm or less, an apex angle α of the nose R portion is 50° or greater and 95° or less, a rake angle β at a position of a bisecting plane of the apex angle of the nose R portion is 1° or greater and 10° or less, a chamfer provided in a cutting edge portion is a negative land with unequal width, and at least on one side of the negative land with respect to a boundary which is an apex of a nose R portion cutting edge, a width of the negative land gradually decreases from the apex of the nose R portion cutting edge to a position at which the nose R portion cutting edge is connected to a linear cutting edge. Let W1 be the width of the negative land at the apex of the nose R portion cutting edge, and W2 be the width of the negative land at both ends of the nose R portion cutting edge, then the W1 is 0.04 mm or greater and 0.2 mm or less, and a ratio of the W1 to the W2 is 1.5 or greater.

摘要： A method for designing a cutting edge of a cutting element configured for removing material from a workpiece to leave therein a desired end profile (B22,B24,B26). The method comprises the steps of modeling a desired end profile (B22,B24,B26) of the workpiece, the profile having a longitudinal axis and being defined by a bottom surface (B12), a side surface (B16) and an adjustment surface (B14) extending therebetween; defining a lead profile plane (RPL) and an trail profile plane (RPT) spaced therefrom, each of the planes being oriented perpendicular to the longitudinal axis; determining a profile contour defined by the intersection line between the end profile (B22,B24,B26) and the lead profile plane (RPL). The contour profile includes a bottom contour, an adjoining contour and a side contour defined as the intersection lines between the lead profile plane (RPL) and the bottom surface (B12), the adjustment surface (B14) and the side surface (B16) respectively; designing a rake surface and a relief surface, the intersection line between which defines a cutting edge lying in the adjoining surface (B14) and spanning between the lead profile plane (RPL) and the trail profile plane (RPT). The cutting edge is designed such that in any reference plane (RP; FIG. 6A) oriented perpendicularly to the cutting edge, the intersection between each of the rake surface and the relief surface with the reference plane (RP) defines a respective rake line (RK; FIG. 7) and relief line (RF; FIG. 7), the angle (θB) between the lines RK,RF) being equal to or smaller than a similar angle (θB) taken along each of a plurality of similar reference planes (RP) disposed between the reference plane (RPn) and the lead profile plane (RPL).
