Abstract

This study investigates the effect of machining parameters on the surface roughness in milling AISI 4340 with cutting speeds of 160- 240 m/min, feed rate of 0.05- 0.15 mm/tooth and depth of cut of 0.1- 0.5 mm under dry and cryogenic conditions using a carbide cutting tool. The results found that the Ra measured for dry and cryogenic conditions were 0.20- 0.38 µm and 0.18-0.27 µm respectively. The (ANOVA) analysis found that the feed rate has significant influence and the utilization of the cryogenic technique helps to improve the surface roughness up to a maximum of 24% as compared with the dry milling.
