ABSTRACT:
A method of modified gear cutting of a globoid worm gear. A worm wheel gear cutting tool employs a conical cutting surface which is substantially the same as the conical surfaces of the teeth of a cooperating globoid worm wheel. The worm wheel is the reciprocal image of the conical cutting surface of the tool. A worm gear is cut by imparting to the cutting tool a motion defined both by the distance between the axis of the worm gear to be cut and the axis of rotation of the cutting tool as well as the speed reduction ratio which constitutes the ratio of the speed of rotation of the cutting tool to the speed of rotation of the worm gear.
