Studies on surface roughness evaluation using machine vision

Abstract

Surface finish of work piece enhances the appearance and overall newlinequality of the component The properties of the surface can significantly newlineaffect friction wear fatigue corrosion thermal conductivity etc Hence newlineinspection of the surface finish is essential for product quality control newlineMajority of the commercial surface roughness measuring instruments are of newlinecontact type and are widely accepted for inspection But its inability for faster newlineevaluation and its incompatibility for automation have led to alternate newlinetechniques for faster measurement Machine vision is tried as substitute for newlineroughness instruments Many investigations are being carried out to evaluate newlinesurface roughness using machine vision newline newline
