Abstract

Electrochemical Honing process (ECH) is a modification of conventional honing techniques whereby material is removed from electrically conductive workpieces through a combination of anodic dissolution and mechanical abrasion. Eighty percent, or more, of the material removal occurs through electrolytic action. ECH is one of the non-equilibrium processes and is a technique, which in spite of being used in some industrial plants especially to smoothen surfaces, is still not fully described due to the variety of the factors affecting the process. More information about the process is required, especially the effects of the working parameters on the produced surface roughness. This paper reports experimental findings on the effect of important process parameters such as workpiece material, time, applied current, initial working gap, rotational speed, electrolyte type and concentration and tool tip shapes on surface quality and metal removal rate (MRR). A special designed honing test rig , which is developed at the laboratory, was used. The surface roughness and (MRR) are measured. The experimental results are a useful guideline for the user for proper selection of conditions for obtaining a good surface quality.
