Abstract

In machining of parts, surface quality is one of the most specified customer requirements. Major indication of surface quality on machined parts is surface roughness. Therefore, this study on hard turning process of Ti-6Al-4V aims to investigate the surface roughness mechanism of the hard turning process, determine any significant of arameters that affect the surface roughness mechanism and utilize statistical tool for the analysis of the surface roughness mechanism. This study mainly focused in the investigation on cutting parameter which are feed rate, depth of cut,cutting speed using coated and uncoated cutting tool type. The experimental utilizes the Design of Experiment (DOE) as the approach to develop and analyze the whole study.By utilizing Okuma LCS-15 CNC Lathe machine, 24 numbers of runs was carried out and measured by using surftest SJ-301. The result shown that for uncoated tools, feed rate was the main parameter that effected to surface roughness while for the uncoated tools the surface roughness most sensitive to cutting speed.
