Study The Effect of Cutting Parameters (Cutting Speed, Feed Rate and Depth of Cut) on Surfaces Roughness in Turning Operation

Abstract

This project aims to study the effect of input variables (depth of cut, cutting speed and feed) on the surface roughness of mild steel by using high speed steel tool with cooling liquid. Nine cylinders’ work-pieces from mild steel are used for straight turning them by using a turning traditional machine under different ranges of cutting condition (depth of cut (0.5,0.3, and 0.15) mm, cutting speed (350,500, and 800) rpm, and feed (0.5,0.3, and0.08) mm/rev. The surface roughness is then measured for all samples turned under these conditions. The result showed that the surface roughness generally increases with the increase of both feed and depth of cut, and when cutting speed increased the surface roughness decreases.
