Abstract
Computerized machinability data systems are essential for the selection of optimum cutting conditions during process planning, and they form an important component in the implementation of computer integrated manufacturing (CIM) systems. This paper presents a study of the development of a surface roughness model for turning grey cast iron (154 BHN), using tipped carbide tools under dry conditions and a constant depth of cut. The model is developed in terms of cutting speed, feedrate and nose radius of the cutting tool. These variables were investigated using design of experiments and utilization of the response surface methodology (RSM). A first-order equation covering the speed range 110–350 m/min and a second-order generation equation covering the speed range 80–495 m/min are presented. The results are given in terms of mean values with confidence intervals.
