Abstract
A gear cutting machine and method for fabricating workpieces, especially steering segments, for transmissions having a variable transmission ratio, wherein there takes place between the workpiece and a gear cutter or hob a part-rolling or generating movement composed of a generating rotation about the workpiece axis and a generating displacement transverse to the workpiece axis as well as a to-and-fro cutting movement along the workpiece axis. An additional movement, controlled by a template and directed transverse to the workpiece axis, alters the course of the generating curve of the workpiece. This additional movement controlled by the template constitutes a change of the work position of the gear cutter and which change is directed transverse to the generating displacement.
