Abstract
A tool, a method and a machine for producing a tooth profile by performing a coupled skiving movement between a skiving tool and the workpiece, by rotating the tool about a tool axis of rotation and rotating the workpiece about a workpiece axis of rotation. The tool includes a crown gear, on the front of which a tooth system with a cutting profile is located, which when in use reproduces the tooth profile on the workpiece.
Claims4
A method for producing a tooth profile on a workpiece comprising the steps of performing a coupled skiving movement between a skiving tool and the workpiece, rotating the tool about a tool axis of rotation and rotating the workpiece about a workpiece axis of rotation, wherein the tool comprises a crown gear on the front of which a tooth system with a cutting profile is provided which when in use reproduces the tooth profile on the workpiece, wherein the tool axis of rotation and the workpiece axis of rotation are aligned intersecting each other at an axis intersection angle and wherein an offset is provided between the workpiece axis of rotation and the tool axis of rotation, in order to achieve a cutting speed component in the tooth gap direction of the tooth profile to be created between the workpiece and the tool.
