The machining process is carried out by removing the unused part of the workpiece into chips, so that it takes the form of a workpiece. Milling is one of the most widely used machining processes for component manufacturing. The working process of the milling machine is by slicing/eating the workpiece using a rotating multi-edged cutting tool (multipoint cutter). Coolant is a liquid used to cool and lubricate between the tool and the workpiece during the machining process. The purpose of this study was to analyze the surface roughness of the aluminum alloy milling process on the effect of cooling. In this study, dromus, dexlite, and kerosene coolant were used. With a feed motion speed of 47 mm/minute, a feed depth of 0.5 mm, and a rotational speed of 1250 Rpm, this roughness test uses the Surface Roughnes Test tool. In the use of dromus coolant, the value of Ra = 1.441 μm was obtained. In the use of dexlite coolant, the value of Ra = 1.353 μm was obtained. In the use of kerosene cooling fluid, the value of Ra = 0.757 μm was obtained. From the results obtained, it can be seen that the use of kerosene cooling fluid is the best. © 2024 Author(s).
