Aspects such as tool life and wear, surface finish, cutting forces, material removal rate,
power consumption, cutting temperature decide the productivity, product quality, overall economy in
manufacturing by machining and quality of machining. The present paper is an experimental study to
investigate the effect of cutting parameters (cutting speed, depth of cut and feed) on tool wear,
surface roughness and material removal rate (MRR) during dry turning of AISI 52100 steel. Turning
experiments were conducted with cutting speeds: 250, 300, 350 m/min, feeds: 0.15, 0.2, 0.25
mm/rev and depth oh cuts: 0.5, 1.0, 1.5 mm. The experimental layout was designed based on the
Taguchi’s L9 (34) Orthogonal array technique and analysis of variance (ANOVA) was performed to
identify the effect of the cutting parameters on the response variables. The results revealed that
cutting speed (61.17%) is only the significant parameter on tool wear. On the other hand, cutting
speed (59.42%) was found to be the dominant parameter among controllable parameters on surface
roughness followed by feed (24.3%). However, depth of cut (78.8%) only showed significant
parameters for material removal rate (MRR). Finally, the relationship between cutting parameters
and the performance measures (tool wear, surface roughness and material removal rate) were
developed by using multiple regression analysis.
