Abstract
Electrochemical machining with an oscillating electrode and pulsed current (PECM) is an innovative manufacturing process for the production of tools and machine elements with highest precision requirements. Currently structure sizes < 1 mm and a flatness of < 5 µm are achievable with PECM. Machining of circumferential surfaces, however, is only possible with substantially reduced precision, which strongly limits the applicability of the method in particular for the production of rotationally symmetrical workpieces. During the conducted investigations, a combination of the pulsed electrochemical machining process with a turning device is explored. The aim of this work is to investigate different machining variants by means of a precise electrochemical turning. Specifically, the variants cylindrical turning and profile turning were successfully demonstrated.
