Paper Title
Study on Surface Optimization in CNC

Abstract
Surface finish plays a vital role in the quality of product. It is necessary to have good surface finish to improve the quality standards of any product. This review paper represents the study of Surface Optimization in CNC. Study on various CNC machining techniques using different techniques such as MMR optimization, Response surface methodology, Principle component analysis, grey relation analysis and Taguchi method was carried out. The parameters that effect surface roughness were optimized based on the analytical reports of the inputs given and its response on surface finish. Keywords - CNC Milling, Surface Optimization, Surface Roughness.
