Abstract
A method for manufacturing gear wheels, specifically transmission gear wheels, is disclosed. An embodiment of the method includes the following steps: a) preparation of a base body for a gear wheel, b) electrochemical processing of the base body by a precise electrochemical machining process (PECM process), where several recesses running between the teeth of the gear wheel are made simultaneously electrochemically to manufacture the teeth of the gear wheel.

A method for producing gear wheels, comprising the steps of:
- a) preparation of a base body for a gear wheel;
- and
- b) electrochemical processing of the base body by a precise electrochemical machining process, wherein to manufacture teeth of the gear wheel several recesses running between the teeth are made electrochemically at a same time by several working electrodes moving simultaneously into the base body by way of a relative radial motion between the base body and the working electrodes.
A method for producing a transmission gear wheel, comprising the steps of:
- preforming a base body;
- and
- machining the preformed base body by a precise electrochemical machining (PECM) process to form teeth of the gear wheel, wherein the PECM process utilizes a plurality of electrodes and wherein the electrodes move relative to the preformed base body in a radial direction to form a respective recess between adjacent teeth of the gear wheel.
