Abstract

This paper proposes a generally applicable numerical algorithm for the simulation of two dimensional electrode shape changes during electrochemical machining processes. The computational model consists of two coupled problems: an electrode shape change rate analysis and a moving boundary problem. The innovative aspect is that the workpiece shape is computed over a number of predefined time steps by convection of its surface with a velocity proportional and in the direction of the local electrode shape change rate. An example related to the electrochemical machining of a slot in a stainless steel plate is presented here to demonstrate the strong features of the proposed method.
