Electrochemical griding machining

Mechanical Engineering

Electrochemical Machining (ECM) has established itself as one of the major alternatives to conventional methods of machining difficult - to - cut materials of and/or generating complex contours, without inducing residual stress and tool wear. The need for complex and accurate three dimensional (3-D) micro components is increasing rapidly for many industrial and consumer products. Electrochemical machining process (ECM) has the potential of generating desired crack free and stress-free surfaces of micro components. This paper reports a study of pulse electrochemical micromachining (PECMM) using ultra short (nanoseconds) pulses for generating complex 3-D microstructures of high accuracy. A mathematical model of the micro shaping process with taking into consideration unsteady phenomena in electrical double layer has been developed. The software for computer simulation of PECMM has been developed and the effects of machining parameters on anodic localization and final shape of machined surface are presented.
