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.
