Abstract: Roughness consists of the irregularities of the surface texture, usually including those irregularities that result from the actions involved in the production process. Surface roughness is an important measure of the quality of a machined product and a factor that greatly determines manufacturing cost. In this work,in order to estimate surface quality and dimensional precision properties in advance, theoretical models are employed making it feasible to do prediction in function of operation conditions and machining parameters such as feed speed and depth of cut etc. The need for statistical method like DOE for studying the relationship between the machining parameters is because of this need for prediction. It is a analysis technique which uses the regression method to find out the relationship between various factors in a DOE setup depending upon the interactions of the predictor variables and the response variables which is performed in the experiments. The research in this domain will help advance further investigations into the relationship between the machining factors and the surface quality of the machined components. The DOE using Taguchi’s method and statistical study of the experimental data helps to understand the interaction between various factors like speed, feed and depth of cut in the machining.

1. INTRODUCTION The surface finish of machined components has considerable impact on some properties such as wear and fatigue strength. Thus, the quality of the surface is truly important in the evaluation of the productivity of machine tools and mechanisms of production, and mechanical components. Fixing a proper cutting condition is really important regarding this because these determine surface quality of manufactured components. In order to know surface quality and dimensional precision properties in advance, it is always better to employ mathematical models making it easier to do prediction in function of operation conditions.The mechanism for the finalisation of surface roughness is very dynamic, complicated, and process dependent so that it is very difficult to calculate its value through theoretical or calculation based analysis.This presents the need for statistical method like DOE for studying the relationship between the machining parameters and roughness of surfaces.
