Abstract
Surface quality in the milling process can be influenced by using cutting fluid. This research examines the effect of using biolubricants as a substitute for commercial cutting fluids on the wear and roughness of mild steel after the milling process with spindle speeds of 500 Rpm and 930 Rpm with a cutting depth of 0.3 mm. This research was carried out with 3 experimental setup in the milling process, the first without using cutting fluid, the second using commercial cutting fluid and the third using biolubricant. The trans-esterified waste cooking oil is found to consist 57.12% esterified fatty acids with viscosity at 40℃ is 19 cSt, at 100℃ is 3.825 cSt, density of 0.836 g/mL and flash point of 29 ℃. The surface roughness results on three mild steel samples show that the use of cutting fluid has an influence on the resulting surface roughness, characterized by several scratches and textures. The highest roughness value at 500 Rpm is obtained with a value of 0.887 µm without using cutting fluid and at 930 Rpm is obtained with a value of 2.793 µm without using cutting fluid. While for lowest surface roughness value, at 500 Rpm is obtained with a value of 0.637 µm by using biolubricant and at 930 Rpm is obtained with a value of 0.300 µm by using biolubricant as well. The use of biolubricants produces better surface roughness compared to using commercial cutting fluids or without using cutting fluids.
