DEFINITION

Classification: 409/11

Hobbing:

(under subclass 10) Apparatus or method in which the cutting tool is adapted to turn about an axis, the cutting tool including at least three radially outwardly directed cutting teeth positioned spirally about the cutting tool axis, each tooth including a cutting edge formed by intersecting planar surfaces one of which surfaces is generally parallel to and radiates from the cutting tool axis, said surface directing a chip formed by the cutting operation away from the cutting edge wherein the cutting tool is rotated and the cutting tool and workpiece are moved relative to each other thus causing the cutting edge to form the intermeshable element on the workpiece, wherein all intermeshable elements of a gear are generated as a continuous operation.
