Abstract

Aluminum is a lightweight metal that is corrosion-resistant, easily formable, and has good thermal and electrical conductivity, making it widely used in household appliances, the automotive industry, and aircraft. One of the processes used is turning. Turning is an important method for achieving high precision, optimal surface roughness, and shaping workpieces into cylindrical forms. The parameter influencing the turning process is the depth of cut, where the depth of cut in the turning process has a significant impact on the workpiece and affects the surface roughness of the workpiece. In addition to affecting surface roughness, the depth of cut also affects tool temperature, Material Removal Rate (MRR), and chip morphology. In this study, the cutting depth was varied at 0.25 mm, 0.50 mm, 0.75 mm, 1.00 mm, and 1.25 mm, with a spindle speed of 1600 RPM and a feed rate of 0.132 mm/rev, using a conventional lathe and an insert tool. The results obtained in this study showed that the highest surface roughness was at a cutting depth of 1.25 mm, measuring 3.3486 μm, and the lowest was at a cutting depth of 0.25 mm, measuring 0.42 μm. The highest tool temperature was obtained at a cutting depth of 1.25 mm, at 102.9 °C, and the lowest was obtained at a cutting depth of 0.25 mm, at 53.4 °C. The highest Material Removal Rate (MRR) was obtained at a cutting depth of 1.25 mm, at 20,229.6 mm³/min, and the lowest was obtained at a cutting depth of 0.25 mm, at 4,256.7 mm³/min. The highest Chip Morphology value was obtained at a cutting depth of 1.25 mm, amounting to 0.90459 mm, and the lowest at a cutting depth of 0.25 mm, amounting to 0.42917 mm
