Investigation of Surface Roughness in High Speed Milling of AISI 1015 Low Carbon Steel Using Response Surface Methodology

Abstract

In the present day, an attempt is made by using response surface methodology to investigate the effect of cutting parameters on surface roughness during face milling of AISI 1015 low carbon steel with uncoated carbide insert at: cutting speed of 300-500 rpm, feed rate of 30-100 mm/min and axial depth of cut of 0.25-1.0 mm. Average surface roughness value were measured and analysed as the response parameters. It was observed that feed rate had the most significant effect on surface roughness. Optimum cutting parameters were observed at 300 rpm cutting speed, 50 mm/min feed rate and axial depth of cut of 0.5 mm.
