A REVIEW BURNISHING PROCESS FOR SURFACE ROUGHNESS AND MICROHARDNESS

A basic understanding of the changes in the condition of the surface is very much required if improvement in product quality is to be attained. Surface integrity (SI) reveals the influence of surface properties and condition upon which materials are likely to perform. Burnishing is a post machining process that is traditionally used to impart specific physical, mechanical and tribological properties on ferrous and nonferrous surfaces. The aim of this work is to present and discuss the various methodologies and strategies that are adopted by researchers to predict surface integrity of burnished component. The presentation of each approach along with its advantages and disadvantages should help both the researchers and practitioners by providing compact yet adequate information to select the one that best suits their needs and specific requirements.
