Abstract:

In this study, an experimental investigation on cutting forces, surface roughness and the hardness of material after machining in turning of 17-4 PH stainless steel using wiper and conventional insert cutting tools with dry cutting condition were presented. The influences of feed rate, depth of cut, and corner radius on surface roughness, cutting force and material hardnesswere examined. In order to optimize the turning process, Taguchi optimization method has been used. The influence of each parameter on obtained results was determined by using analysis of variance (ANOVA). The relationship between dependent parameters and independent parameters were modeled by Regression analysis. The optimal machinability of 17-4 PH stainless steel with coated carbide insert was successfully determined in this study.
