Abstract
An investigation has been made to study the effect of various machining parameters during high speed machining on the workpiece surface roughness. The experiments were carried out taking AISI 1045 steel as the workpiece material and coated carbide tool Five levels of cutting speeds and feed rates were selected. The Taguchi's orthogonal arrays and analysis of variance (ANOVA) were employed to design the experiments, study the performance characteristics and to find the significance and contribution of cutting parameters on surface roughness in high speed turning. It was observed from these experiments that at the higher cutting speeds (240m/min) the best surface roughness results were observed. Cutting speed was found to be most significant factor for surface roughness and contributes up to 76%. The feed rate and interactions between cutting speed and feed rate were observed to have no significant impact. Thereafter optimum parametric combinations were also found.
