DEFINITION

Classification: 409/1

GEAR CUTTING:

(under the class definition) Apparatus or method particularly adapted to form an element on a workpiece body, which element is intended to intermesh with an element on another body whereby motive force may be transmitted from one of the bodies to the other.

(1) Note. A gear pump rotor is considered to transmit force to the other rotor. Also, the drive element sprocket of a gear driven chain is considered to be similar to a gear tooth.
