ADVANCED SURFACE FINISHING PROCESSES: A COMPREHENSIVE REVIEW & FUTURE RESEARCH DIRECTIONS

摘要

Better surface quality of every component is essential to perform proper functioning and to reduce the losses ofwear and tear in the moving machine parts. Traditional processes do not use for finishing of soft or brittlematerial, due to high abrading force it produces poorer surface. In a competitive business environment,manufacturing industries are facing challenges in the machining of ceramics, super alloys and composites whichrequires a high precision level and superior surface quality with optimum machining cost. Advanced finishingprocesses are capable enough for precise finishing of soft or hard materials without damaging its surface orsubsurface. This paper presents a comprehensive literature review the state of the art technology of highperformance surface finishing processes used in manufacturing industries. The processes are divided into threemain categories: traditional, advanced and hybrid finishing processes. A limited research has been reported onadvanced processes in which finishing force can be easily controlled externally by magnetic field or any othermeans. A finishing medium is used in all these processes called magnetorheological fluid, which is a mixture ofabrasive particles, CIPs, binder and additives. Rheological properties of magnetorheological fluid can becontrolled externally by varying magnetic field. Due to control of force acting on an abrasive particles andmaterial removal rate also controlled. Finally, the drawbacks and missing aspects of the related literature arehighlighted and a list of potential issues for future research directions is recommended.
