The machining process using a milling machine on titanium requires a cooling media to cooling the cutting tool and workpiece. The application of cooling media from organic materials can reduce the use of synthetic oil as cooling media which is difficult to decompose naturally. Palm oil which is one of the most widely produced vegetable oils in Indonesia. The use of palm oil as a coolant has been widely carried out, to improve the performance of palm oil as a cooling media by increasing the ability of palm oil to absorb heat. In this research, TiO2 particles and solid lubricant were added. The milling process was carried out at 250, 370 and 600 rpm, while the TiO2 content was 0,25; 0,50 and 0,75 grams/100mL vegetable oil. The highest surface roughness occurred in a 0,05 grams TiO2 (0,585 µm), while the lowest occurred in a mixture of 0.1 gram of graphite at 0,338 µm. The effect of TiO2 content on decreasing the surface roughness. © 2024 American Institute of Physics Inc.. All rights reserved.
