摘要： An indexable cutting insert (10) having a top surface (12) including a substantially planar central portion (48), a substantially planar bottom surface (14), and a plurality of side surfaces (16, 18, 20, 22). A long cutting edge (24, 26), a corner radius cutting edge (28, 30), a facet radius cutting edge (32, 34), and ramping cutting edges (36, 38) are defined at an intersection between the top surface (12) and one of the side surfaces (16, 18, 20, 22). A margin (87, 89) extends around a nose radius of the side surfaces (16, 18, 20, 22). A margin (87, 89) extends around a nose radius of the cutting insert (10) and blends into a flat surface (94, 96). A margin angle, C, formed by the margins (87, 89) is less than a seating angle, B, formed by the flat surfaces (94, 96). The top surface (12) includes a plurality of upward sloping radius blends (50, 52, 54, 56, 58, 60, 62, 64) extending between the substantially planar central portion (48) and a plurality of upward sloping rake faces (70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92) extending between a respective radius blend and its respective cutting edge such that the rake face forms an angle, A, of between five and twenty-five degrees with respect to the central portion (48) of the top surface (12).

摘要： A toolholder (10) has a pocket (20) adapted to receive a double-sided on-edge cutting insert (25), wherein the corners (39 a-d) of each side (37 a-d) of the insert are radially shifted with respect to one another and has mounting pads (78, 80) preferably mounted about the sides of the cutting insert. The relief area for the corners (39 a-d) of the insert (25) is selectively fabricated to maximize the length of the support pads (78, 80) within the pocket (20) of the toolholder (10).

摘要： A cutting tool having an outer surface with a plurality of inserts connected to a distinct pocket extending generally radially on the outer surface. The cutting inserts are arranged in a helical array on the outer surface in a manner that at least one cutting edge of each cutting insert is spaced in an angular circumferential direction from the pocket of the next adjacent cutting insert. The spacing of the inserts is such that a distinct point on the each one of the one or more cutting edges define part of a layout line having a non-uniform slope.

摘要： A cutter system (10) that is designed to create a continuous cutting true helix while having cutting inserts (14) that are indexable on at least two cutting edges (66 and 68) by rotating the cutting insert. High positive radial and axial rakes enable free cutting machining with a fine finish and low horsepower consumption. The back face (40) of the insert (14) is substantially flat and is used for face contact on lockup with a mounting pocket (34) on the cutter body (12) when the insert screw is tightened. The mounting pocket (34) is designed for ease of manufacture to limit tolerance buildup to ensure repeatable insert (14) positioning and to maintain accuracy for a fine cutting finish. The insert screw hole (46) is placed in the cross hole location for allowing an unobstructed cutting face and a larger diameter center core in the cutter body (12). The larger core creates maximum strength and allows longer cutting lengths. Prior to grinding, the insert blank can be used for multiple diameters of cutters. After grinding the insert blank, the inserts are made specific to the cutting diameter for which they were ground or a compromised grind may be employed for use with multiple cutting diameters.

摘要： A rotary cutting tool (10) such as a helical end mill, having pockets (16) arranged to overcome harmonic vibrations. The tool (10) has at least two and in one embodiment all three of three spacing irregularities. In the first irregularity, columns of pockets (16), typically associated with flutes (24, 26, 28), are staggered circumferentially out of even spacing. In a preferred embodiment having three flutes (24, 26, 28), the flutes are mostly not centered on one hundred twenty degree intervals. In the second irregularity, at least some pockets (16) are arranged at different radial rake angles. In the third irregularity, at least some pockets (16) are arranged at different axial rake angles.

摘要： A high-speed milling cutter (10) includes a shank (12), a front portion (14), and a transition surface (16) between the shank (12) and the front portion (14). The cutter (10) also includes an insert pocket (20) having a bottom surface (22) and side surfaces (24, 26). The bottom surface (22) includes a raised boss (28) for supporting a cutting insert (30). The cutting insert (30) has a top surface (32), a bottom surface (34) and side surfaces (36, 38, 40, 42). The cutting insert (30) includes a primary cutting edge (44, 46) formed at an intersection between the top surface (32) and two of the side surfaces (36, 38, 40, 42). The top surface (32) of the cutting insert (30) includes a concave or dish-shaped topography that is designed for high-speed milling operations of a metallic work piece. The cutting insert (30) also includes a bore (76) in the bottom surface (34) capable of receiving the raised boss (28) for securely retaining the cutting insert (30) within the insert pocket (20), and reducing bending moment on retaining screw 64 during high-speed milling operations.

摘要： A cutter system (10) that is designed to create a continuous cutting true helix while having true helical inserts (14) that are indexable on at least two cutting edges. The shape of the insert (14) allows an interlocking overlap of the cutting edges (66 and 68) for an all effective true helical cut. The helix ground into the insert faces creates a smooth cutting action as a solid helical endmill. High positive radial and axial rakes enable free cutting machining with a fine finish and low horsepower consumption. The back (34c) of the insert (14) has a diamond shaped island (42) that is used for locating the insert in the mounting pocket of the cutter and is used for face contact on lockup when the insert screw is tightened.
摘要翻译：一种切割器系统（10），该切割器系统（10）被设计成产生连续切割真正螺旋，同时具有可在至少两个切割边缘上转位的真正的螺旋插入物（14）。插入件（14）的形状允许切割边缘（66和68）的互锁重叠，以进行全部有效的真正螺旋切割。螺旋刀片磨削到刀片表面时，可以形成平滑的切削行为，如同实心螺旋铣刀一样。高正向径向和轴向耙可实现精加工和低马力消耗的自由切削加工。插入件（14）的背部（34c）具有菱形岛（42），该岛用于将插入件定位在切割器的安装凹部中，并且当插入螺钉被拧紧时用于在锁定时进行面接触。
