摘要： This helical broach forms a twisted groove at the inner circumference of a machined hole of a workpiece by a plurality of cutting teeth, the plurality of cutting teeth include a plurality of circumference cutting teeth which are arranged on the tip-end side of the broach body, and include a plurality of tooth thickness cutting teeth which are arranged on the rear-end side of the broach body. The plurality of tooth thickness cutting teeth include cutting edges and guiding edges, respectively. The tooth thickness cutting tooth positioned closest to the rear-end side of the broach body is provided with the guiding edge instead of the cutting edge at the intersecting ridge part between a rake face and a lateral surface facing one wall surface of both groove wall surfaces of the twisted groove of the workpiece.

摘要： A helical broach 1 for roughing includes a cutting tooth part 30 in which n spline teeth 31 are arranged side by side in an axial direction. The spline teeth 31 each include cutting teeth 32 which are arranged at a predetermined helix angle. The cutting teeth 32 each have an acute angle portion and an obtuse angle portion on both sides thereof in a circumferential direction. The cutting teeth disposed on the first to n−1th spline teeth 31 (S1 to Sn−1) in the circumferential direction are each formed in such a way that its height on the acute angle portion side differs from that on the obtuse angle portion side. The cutting teeth (Sn) of the nth spline tooth (Sn) are each formed in such a way that its height stays constant in the circumferential direction.

摘要： A machining system includes a support configured to retain an article, such as a rotor disk, having an area, such as a surface of a slot in the disk. A cutting tool, for example, a broach, is movable relative to the support to cut the area. A heating member, such as a laser, is configured to locally heat the area of the article. In one example, the cutting tool includes a body having a cutting edge. The heating member is supported by the body and is configured to provide heat adjacent to the cutting edge. The cutting edge cuts the locally heated area while the area is still heated.

摘要： A broach assembly includes an elongated base having a central upward projection and a pair of side flanges and a tapered undersurface. Releasably mounted on the projection are multiple tool holders spaced along the length of the base. The tool holders mount cutters for engaging active surfaces of the wedge slot as the broach assembly is passed through the wedge slot. Shims may be interposed between the tool holders and base to increase the elevation of the cutting surfaces relative to the undersurface of the base to progressively increase the bearing pressure of the cutting surfaces against the active surfaces of the slot during multiple passes of the broach assembly through the wedge slot.

摘要： The broach assembly includes alternate spacers and cutters arranged in a sub-assembly having a lead at a leading end and a lag at a trailing end. The cutters have side margins in excess of the margins of the spacers for cutting material from the dovetail slots of the turbine wheel as the broach assembly passes through the slots. The bottom or apices of each spacer and cutter are tapered to form a continuously tapered surface along the bottom of the broach assembly. Upon passing the broach assembly through the slot, the assembly is progressively displaced in a radial outward direction to progressively cut the active dovetail slot surfaces. Shims may be disposed in the bottom of the slot to further displace the broach assembly radially outwardly in multiple passes.

摘要： Herein disclosed are a method of forming a rectangular groove having accurately rectangular cross-section at an apex of an angular workpiece, and a combination tool therefor. The method comprises the steps of broaching the apex portion of the angular workpiece to form a preparatory dove-tailed groove having its bottom width substantially equal to that of the finally obtainable rectangular groove of a desired width and its top width slightly smaller than said desired width, and burnishing said preparatory dove-tailed groove to finally obtain the rectangular groove having its bottom and top of said desired width. The method may further comprise the step of initially broaching the apex portion to form a preparatory rectangular groove having its width slightly smaller than the top width of the dove-tailed groove.
