Determination of Ceramic Cutting Tool Performance on Machining of Steel (PMD23) Produced by Powder

Abstract

This study aimed to determine optimum cutting parameters for recovering the best surface roughness during PMD 23 powder metal machining with ceramic sharp cutting tool at CNC turning center. Experiments for this aim were carried out on 27 samples in 80 mm diameter and 200 mm length prepared at turning center by application of cutting parameters determined with Taguchi method. Three different cutting speeds (200, 350, 500 m/min.), three different feed rates (0,1–0,2–0,3 mm/rev) and three different tool nose radius (0,4-0,8-1,2 mm) were used and depth of cut was applied stable as 0,8 mm in the experiments. Later, surface roughness of experiment sample and the roughness change was evaluated with respect to cutting speed, feed rate and tool nose radius. Variant analysis (ANOVA) were used to investigate characteristics of the processes. As a result of the experimental study, it was found out that feed rate and tool radius of cutting parameters had an effect on surface roughness, but the effect of cutting speed was not significant.
