Abstracts: The resurgence of the high quality and precision parts by manufacturing industries has enabled the development of ultra precision machine tools. Surface roughness and tolerances are the most critical quality measures of any mating mechanical parts produced. The quality evaluation requirement of manufactured parts is becoming the prime factor as it determines not only the esthetics values, but also the lifespan and function of its purpose. Grinding is one the most popular methods of machining hard materials which widely known as random point cutting. The main aim of this experimental work is to investigate the significant parameter(s) in surface grinding which affect the machined surface roughness. Two work materials, namely, mild steel and carbon steel have been investigated with two variables; feed rate and depth of cut for the response of surface roughness. Statistical approach using Design of Experiment (DOE) has been carried out in this investigation.
