Transient simulation of an electrochemical machining process for stamping and extrusion dies

Precise electrochemical machining (PEM) is a non-conventional machining technology, based on anodic dissolution of metallic workpieces. In this study an additional extension of the precise electrochemical machining with a precise angle-controlled cylinder positioning is aimed. Due to the help of the angle-controlled cylinder positioning, with PEM e.g. stamping and extrusion dies can be machined. To investigate the modified process transient simulation models have been developed. The models are based on the modules deformed geometry, electric current and wall distance to compute the resulting ablation.
