Method for producing conical or hypoid wheels using the plunging process

摘要

A method of chip-removal machining a tooth gap of a work piece includes executing a first substantially linear plunging movement of the cutting tool along a first plunge vector and machining a region of the work piece near a tooth head of a first tooth flank of the tooth. A substantially transverse movement of the tool along a transverse vector is then executed to machine a region of the work piece near a tooth head of the second tooth flank of the tooth. A second plunging movement of the cutting tool along a vector path is then executed, to an end point of the second plunging movement that lies at a position of the work piece corresponding to the slot depth of the tooth gap to be fabricated. The cutting tool is rotated about an axis of rotation thereof during execution of these steps.

1. A method of chip-removal machining of at least one tooth gap of a bevel gear or hypoid gear work piece comprising rotating a cutting tool having a first main cutting edge and a second main cutting edge about an axis of rotation of the cutting tool, and performing the following steps during said rotating step:
(a) moving the cutting tool in a first relative linear plunging direction along a first plunge vector that extends substantially perpendicularly to a foot cone of the work piece, to a position in the work piece that is more than 10% of a slot depth of the tooth gap to be fabricated, thereby machining with the first main cutting edge a region of the work piece near a tooth head of a first tooth flank of the tooth gap; (b) moving the cutting tool relatively transversely along a transverse vector so as to move the second main cutting edge in a direction of a second tooth flank of the tooth gap, and machine a region of the work piece near a tooth head of the second tooth flank of the tooth gap; and (c) moving the cutting tool in a second plunging movement along a vector path to a position in the work piece approximately corresponding to the slot depth of the tooth gap to be fabricated.
