With a method for cutting a groove-shaped recess in a workpiece, a cutting tool for a machine tool is provided on a workpiece. The cutting tool is displaced into a cutting position, in which the cutting tool is in engagement with the workpiece. The cutting tool in engagement with the workpiece is displaced relative to the workpiece for cutting the groove-shaped recess. Upon cutting, a chip is produced with a predetermined maximum chip length that is less than a total length of the recess to be produced.

An apparatus and corresponding method for machining at least one spline in an aeronautical component. The apparatus comprises a holder defining an axial direction about which the holder is moveable, and a cutting insert attachable to the holder. The apparatus further comprises a coupling for attaching the cutting insert to the holder about a second direction that is perpendicular to the axial direction of the holder. The holder may comprise a first alignment feature for orientating the cutting insert at a single orientation with respect to the holder. The cutting insert may comprise at least one cutting tooth, wherein each cutting tooth comprises a cutting edge. The cutting insert may comprise a first datum surface which is spaced from each cutting edge by a respective predetermined spacing.

This invention relates to an agricultural disc for use in agricultural work, such as to open furrows in the soil for sowing or to prepare the land for tillage and grinding, comprising two surfaces, a cutting circular perimeter edge and a plurality of notches located on a first surface of said agricultural disc, distributed in a circular matrix shape concentric to the agricultural disc, located adjacent to the perimeter edge. The invention also comprises the process for manufacturing the agricultural disc comprising a step of creating a plurality of undulations in a circular disc and a step of shaving or straightening via machining the crests generated on a second surface when the undulations are generated.

A drive assembly for a motor vehicle drive train includes a shaft including a plurality of axially extending splines defining an outer circumferential surface, and a planet carrier non-rotatably fixed to the shaft by the axially extending splines. The planet carrier and the shaft are axially constrained with respect to each other by a radially inwardly extending material of the planet carrier axially contacting a radially extending surface of the shaft.

A cutting disk for workpieces, particularly workpieces of fiber-reinforced composite materials, has a base body which is provided at least in some areas with a circumferential toothing and with a flank toothing arranged on at least some areas and on at least one lateral surface. At least with the majority of circumferential teeth, the main cutting edges do not directly encounter the main cutting edges of the adjacent flank teeth, and the main cutting edges accordingly do not define a common rake face.
