Electrochemical Honing - a Novel Technique for Gear Finishing

Abstract

This paper reports on high-precision finishing of gears by Electrochemical Honing (ECH) process. It is one of the most potential micro-finishing process in which material is removed by anodic dissolution combined with mechanical abrasion of bonded abrasive grains. The precision finishing of gears by ECH is a productive, high accuracy, long tool life gear finishing process. The present study contains a detailed description of the process principle, influencing parameters, process capabilities, equipment details, applications, effects of input parameters, developed regression models, surface integrity aspects of machined surface and comprehensive literature review of past research work on the ECH of gears along with some guidelines for further research with an objective to revive the interest of the global research community to mature this process further.
