Cutting blade pressure angle changes or corrections in power skiving cutters (20) can be realized without the need tor a tool geometry change. An axial shift (26) of the blade reference point (24) will shift the existing involute on the blade profiles (22, 23) into a different radial location. An accompanying shift (AR) of the reference involute profile (30) by approximately the same amount and in the same direction will re-establish the relationship between work gear and cutter. The resulting work gear geometry has the same radial location of the slots, with the same slot width and the same tooth thickness but with a changed pressure angle.

A low profile peripheral cutter (18) with stick blades (6). The cutter has a cutter body (30) and a flexible clamping disk (20) to clamp all blades. The flexible clamping disc includes a slot (24) between each cutting blade (6) in order to provide a plurality of blade clamping web wings (26) each of which acts like a deflection beam to hold the blades in position. Preferably, each web wing (26) covers one stick blade (6) and each web wing has two contacting pads (36, 38) to press each blade into its seating surface (44, 46) thereby holding the blade in position.

A power skiving tool includes a basic body, which is equipped with a plurality of replaceable cutting inserts, by means of which chips can be carved or peeled out of a workpiece with the purpose of forming, for instance, teeth. The individual cutting insert is formed with only one cutting edge) and has a rear end in the form of a shoulder surface, against which an adjusting mechanism is pressed for the fine adjustment of the radial position of the cutting insert in relation to the basic body. On the underside of the cutting insert, there is in addition a control means, e.g. a serration connecting surface, which interacts with the corresponding control means in the appurtenant seat in the basic body. In addition, the invention concerns a power skiving cutting insert as such.

Herein a cutting insert for a power skiving tool is disclosed. The cutting insert includes an insert body having a bottom surface extending in a first plane, and a body axis extending substantially in parallel with the first plane. The insert body has a cutting end portion and opposite thereto, an abutment surface. The abutment surface extends substantially perpendicularly to the body axis and to the first plane. The cutting end portion is provided with a first and a second cutting edge, the first cutting edge and the second cutting edge being directed in a same cutting direction. Herein, further a power skiving tool including such cutting inserts is disclosed.

An insert, a housing, and a power skiving assembly each configured for use in a power skiving process is provided. The insert includes multiple cutting edges such that when one of the cutting edges is no longer suitable for use in a power skiving process, an orientation of the insert with respect to the housing can be changed so that another of the multiple cutting edges is aligned with a work piece upon which the power skiving process is being performed.
