Abstract: Development of empirical models in turning operation has been a major activity in metal cutting research. This paper presents an application of central composite face centred (CCF) and L18 (21 × 37) orthogonal array designs for developing cutting force and surface roughness models in case of turning AISI 1015 steel with HSS tool. Three process parameters namely cutting speed, feed, depth of cut and three tool parameters namely side cutting edge angle, inclination angle, normal rake angle were considered in developing the cutting force and surface roughness models. Each parameter was set at three levels. Based on the experimental data, mathematical models in terms of process and tool parameters were developed using multiple linear regression. Finally, central composite and orthogonal array designs are compared with respect to effect analysis and empirical model building. Confirmation tests were performed to verify the predictability of the developed models.
