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.
