Abstract:
1. Method for soft machining of bevel gears having the following steps: introduction of a bevel gear blank to be machined into a device, feeding an end-milling cutter used as a pre-gear cutting tool by executing a relative movement between the bevel gear blank and a machining arm of the device, which arm has a first tool spindle for receiving a cutter head used as a bevel gear finishing tool on a first side of the arm and a second tool spindle for receiving the end-milling cutter used as the pre-gear cutting tool on a second side of the arm, pre-machining of the bevel gear blank using the end-milling cutter, by putting it into rapid rotation and plunging it into the bevel gear blank in a generating movement to cut a predefined number of tooth gaps on the bevel gear blank in an approximate desired position and having approximate desired dimensions, pivoting the machining arm and executing a relative feed movement to bring the cutter head into a starting position, post-machining of the bevel gear blank using the cutter head, the cutter head being put into a slow rotation and machining the bevel gear blank by a rolling movement.
