The tool performance in milling SUS 316 material by using an uncoated tool in the wet cutting condition was studied in this research work. The objective of this research was to evaluate the tool performance in terms of tool wear and tool vibration by achieving suitable cutting condition and cutting edge radius. The uncoated carbide end mill tool was sponsored by HPMT Sdn. Bhd. where the diameter of the tool was 6 mm with 4 flutes with cutting edge radius varying between 30 μm, 40 μm and 50 μm. The dimension of the SUS 316 material was 140 mm in length, 110 mm in width and 50 mm in height. The experiment was also conducted with different width of cut which is 0.1 mm, 0.6 mm and 1.2 mm. The spindle speed, feed rate and depth of cut had been fixed to constant which is 4500 rpm, 350 mm/min and 6.0 mm respectively. The experiments were run on a 3-axis CNC machine which is the Mazak Vertical Center Nexus VCN 410A-II. The experiments were designed to have nine sets of experiment. The tool wear was observed and measured by using a digital microscope which is the Dino Lite Premier AM4113ZT. The tool vibration was measured by using an accelerometer Bruel & Kjaer Type 2250-W. After running the experiments, the data was recorded and transferred to the Design of Experiment software for analysis purpose to obtain evaluated cutting parameters. Based on experiment’s results, cutting edge radius of 30 μm with 0.1 mm width of cut had better wear resistance and lowest tool wear reading among nine of the experiments. The evaluated cutting parameter that was selected by DOE software was 0.1 mm width of cut with a cutting edge radius of 30 μm which was selected based on the lower tool wear results.
