Abstract: 

This paper present an experimental study of hard turning with PVD coated carbide tool of AISI 52100 bearing steel, with the hardness of 45-47 HRC. The main purpose of given study is to establish the effect of cutting condition on cutting forces and surface roughness. The main focused on relationship between cutting parameter i.e. cutting speed , feed and depth of cut and machining output variables i.e. cutting forces and surface roughness through the response surface methodology i.e. central composite rotatable design. The effect of cutting parameters on machining output variables is to examine using analysis of variance (ANOVA). The quadratic model is drawn by using RSM which was used to find out most favorable machining parameters based on observed facts i.e. cutting forces and surface roughness. The machining of work piece material was conducted using super fine PVD coated carbide tool insert. Cutting forces were measured using lathe tool dynamometer and surface roughness was measured using Taylor hobson’s surtronic duo measuring instrument. It was found that at lower feed value, lower depth of cut value and cutting speed of 130m/min we get minimum value of cutting forces, surface roughness and tool wear.
