    چکیده انگلیسی:

    The present contribution deals with the study of the effects of cutting speed, feed rate and depth of cut on the performance of machining which traditionally named ‘‘machinability”. The focus is made on the effect of the pre-cited cutting parameters on the evolution of sur- face roughness and cutting force components during hard turning of AISI D3 cold work tool steel with CC6050 and CC650 ceramic inserts. Also, for both ceramics a comparison of theirwear evolution with time and its impact on the surface equality was proposed. The plan-Keywords:Hard turningning of experiments was based on Taguchi’s L16orthogonal array. The analysis of varianceSurface roughness Cutting forceTool wear Taguchi method RSM(ANOVA), the signal-to-noise ratio and response surface methodology (RSM) were adopted.Consequently, the validity of proposed linear regression model was checked and the most important parameter affecting the surface roughness and cutting force components were determined. Furthermore, in order to determine the levels of the cutting regime that lead to minimum surface roughness and minimum machining force the relationship between cutting factors was analyzed. The results revealed that the surface quality obtained with the coated CC6050 ceramic insert is 1.6 times better than the one obtained with uncoated CC650 ceramic insert. However, the uncoated ceramic insert was useful in reducing the machining force.© 2015 Elsevier Ltd. All rights reserved.
