To provide a gear machining device and a gear machining method which achieve machining of tooth flanks having different torsion angles with high degree of accuracy. In a gear machining device, a side surface of a tooth of a gear includes a first tooth flank and a second tooth flank having a different torsion angle from the first tooth flank, a cutting blade of a machining tool has a blade traces having a torsion angle determined based on a torsion angle of the second tooth flank and an intersection angle between a rotation axis of a workpiece and a rotation axis of the machining tool so as to allow the second tooth flank to be machined on the pre-machined first tooth flank.

Methods and apparatuses enabling/improving retractability of a first bevel gear that with at least one second bevel gear forms a transmission, performing: a retractability analysis including: ascertainment whether during the installation in a housing the first gear can be engaged by an axial insertion movement with the second gear and/or the first gear can be separated from the engagement with the second gear by an axial retraction movement, and if a collision results during the engagement or separation between teeth of the gears ascertainment of a flank modification of the teeth of the first and/or second gears to avoid the collision, ascertainment of second machine data of based on this modification, and finish machining in a bevel gear cutting machine to perform the flank modification according to the second machine data on the teeth of the respective gears.

A tool for handling a modular information handling resource may include a drive portion, a first finger mechanically coupled to the drive portion, the first finger configured to apply a first force to a first side edge of the information handling resource when the information handling resource is engaged with the tool, and a second finger mechanically coupled to the drive portion, the second finger configured to apply a second force to a second side edge of the information handling resource opposite from the first side edge when the information handling resource is engaged with the tool. When the information handling resource is coupled to a connector via a bottom edge of the information handling resource adjacent and perpendicular to the side edges, a retention force applied by the connector to the information handling resource overcomes the first and second forces such that the tool releases the information handling resource.

Method for cutting a gear (4) from a metal workpiece (2), in which a tooth flank, still having an oversize compared with its predefined final geometry, of the gear is, in one or more cutting passes in cutting engagement with one or more cutting tools (10) fed thereto, hard-fine finished with a geometrically undefined cutting edge made of cutting grains incorporated in a binder matrix, in order to produce a reflective property, existing in the final geometry, of its surface, wherein, in a cutting pass of a cutting tool (10b), both an elastically resilient mounting of the cutting grains set by its binder matrix acts on this surface property, and a cutting reduction of the oversize by at least 2 m at the tooth flank is realized by a compressive preload, set via the infeed of the cutting tool, to which the cutting engagement is subjected; as well as a gear-cutting tool and a machine tool for this purpose.

The present disclosure includes a shaft and spindle assembly for retaining a part in a part processing assembly. The part is retained on the shaft via a downward force from a part hold-down assembly. The shaft is retained in the spindle assembly that is coupled to a turntable of the part processing assembly. The shaft includes an annular step that abuts against a portion of the spindle assembly to block downward movement of the shaft when the downward force is applied. In this way, the part is retained in a precise location relative to processing nozzles of the part processing assembly even after multiple parts are held down by the part hold-down assembly and processed.

A method of manufacturing a mechanical component made of steel including a surface-hardening phase. The method includes creating a rough form of the component with regions to be hardened, then successive case hardening with cooling without quenching, heating to an austenitizing temperature of the steel by induction heating the zones, and quenching.

A continuous semi-completing method for machining the tooth flanks of a face coupling workpiece using a gear cutting tool having multiple blades. Exemplary methods include a) setting of a first machine setting, wherein an inner cutting edge of an mth blade of the gear cutting tool machines a convex flank of a first tooth gap, and an inner cutting edge of a further blade machines a convex flank of a following tooth gap, until all convex flanks of all tooth gaps are finish machined, and b) setting of a second machine setting wherein an outer cutting edge of an nth blade of the gear cutting tool machines a concave flank of a tooth gap, and an outer cutting edge of a further blade machines a concave flank of a following tooth gap, until all concave flanks of all tooth gaps are finish machined.

Semi-completing single indexing methods for machining the tooth flanks of a face coupling workpiece. A tool is used which includes at least one cutting head having two cutting edges or two grinding surfaces. Exemplary methods include executing at least one first relative setting movement, to achieve a first relative setting, finish machining a first tooth flank of a tooth gap of the face coupling workpiece using a first cutting edge or using a first grinding surface of the tool and simultaneously pre-machining a second tooth flank of the second tooth gap using the second cutting edge or using the second grinding surface, executing at least one second relative setting movement, to achieve a second relative setting, and finish machining the second tooth flank of the same or a further tooth gap using a second cutting edge or using the second grinding surface of the tool.
