Abstract

This study aims to determine the surface roughness of middle steel, aluminium alloy, and brass according to ISO 1302 standards on spindle speed. As well as knowing the chemical composition according to ASTM E415 standards, ASTM E1251, ASTM E478 and knowing rockwell hardness according to ASTM E18 standards, this research method is the process of flat turning on middle steel, aluminium alloy with a length of 200 mm and 40 mm diameter, brass with a length of 200 mm and 20 mm diameter with variations in spindle speed 500 rpm, 1200 rpm, 1810 rpm with a constant feed motion of 0.06 mm / turn and a cutting depth of 0.5 mm. The tools used in this study were Krisbow lathe type KW15 - 486, rockwell hardness testing machine Mitutoyo brand type HR - 400, 00203351 series arun metal scan spectrometer, and surface roughness tester TR200. Chemical composition testing results show that the material used is medium carbon steel, aluminum alloy Al – Mg - Si, and high alloy brass. Rockwell hardness test results show that steel has a hardness of 85.5 kgf/mm, brass at 65.9 kgf/mm, aluminum alloy at 61.2 kgf/mm. Surface roughness test results showed that the value of surface roughness in steel, brass and alumnium values obtained the smallest roughness at a spindle speed of 1810 rpm while the largest surface roughness value was obtained at a spindle speed of 500 rpm.
