Abstract

Recent developments in precision manufacturing along with miniaturization of parts have put strict requirements on edge and surface finishing processes. It not only requires clean and defect free surfaces but also maintain previously generated precision dimensions on advance engineering material. The burr is undesired but inevitable, real productivity killer and amid the most worrying obstructions to mechanization of machining processes, hence affecting quality. Deburring and edge quality is of concern for the performance, cost, safety and appearance of the parts. Over the years electrochemical deburring (ECD) has emerged as a tool for removal of the burrs and retain the requisite edge tolerances exclusive of damaging formerly generated precision dimensions. Conventional ECD process working on the electrochemical principle has been now coupled with faradayic technology to enhance process capability. It is well known that ECD process works for conductive work materials and in specific applications. This review encompasses fundamental principle, parametric analysis and capabilities of the ECD processes that have been evolved through cross innovations. It also critically analyzes mathematical approaches for the modeling of the process in conjunction with their key formulations. Further it discusses the areas which need to be explored.
