The application of stainless steel, especially SUS 316 have been significantly increasing especially in manufacturing area. However, problems such as rapid tool wear and poor surface roughness are a major problem when machining SUS316. The geometry and type of materials of cutting tool during machining SUS 316 plays a significant role in determining the outcome of the machining. This study was conducted to investigate the effect of cutting-edge radius (CER) and width of cut (WOC) on tool wear in milling SUS316 stainless steel. 6 mm diameter of uncoated tungsten carbide having three different values of CER which are 30, 40 and 50 and WOC of 0.1, 0.6 and 1.2 mm were selected as cutting tool in this study. A cutting speed of 4500 RPM, feed rate of 350 mm/min were kept constant throughout this experiment. It has been found that the cutting edge radius of the cutting tools plays a significant impact on the tool life and the surface roughness. It is proved that different CER and WOC values have significant influence on the tool wear and surface roughness while milling SUS 316 and it is concluded that the most optimum parameter combination is between 30 µm CER and 0.1 mm WOC based on the experimental data collected. It executes lower readings for both the imposed wear on cutting tool and the surface roughness of machined SUS 316 after 4400 mm machining length compared to other data of different combinations.
