Abstract

This study examined the effect of cutting parameters on the surface roughness generated during face milling operation of a pearlitic ductile iron using cemented carbide tool. The pearlitic ductile iron used for the study was prepared from scraps of ferrous metals using 100 kg rotary furnace at the Engineering Materials Development Institute (EMDI), Akure, Nigeria. Four cutting parameters were considered for the study, namely; cutting speed, feed rate, depth of cut and cutting fluid flow rate. The experimentation was based on Taguchi’s design approach. The data collected were subsequently subjected to analysis of variance. The average surface roughness of machined surfaces, increased as depth of cut increased. The effect of increase in feed rate and cutting speed was to reduce the average surface roughness, though not statistically significant. On the other hand, surface roughness decreased significantly with increase in cutting fluid flow rate and depth of cut. The average surface roughness value was highest at zero fluid flow rate and lowest at the flow rate of 4 Ɩ/min. The study concluded that out of all four cutting parameters investigated, the cutting fluid flow rate had most considerable positive influence on the surface roughness of a machined pearlitic ductile iron
