Abstract

In this study, the effects of different cutting parameters on surface roughness (Ra) and cutting force were investigated in dry hard turning of 1.2367 hardened (55 HRC) hot tool steel. In this experimental study, the Taguchi method was used for the design of experiments, and a constant cutting depth; three different cutting speeds, and three different feed rates were selected as cutting parameters. The effects of cutting parameters on surface roughness and cutting forces were evaluated by performing an analysis of variance (ANOVA). According to the results, it was observed that the surface roughness value increased depending on the increase in the feed rate. On the other hand, the influence of cutting speed on the surface roughness was negligible. It was seen that the most effective parameter on the radial force (Fy), tangential force (Fy), and feed force (Fz) was the feed rate.
