Abstract :
The lathe is one of the production process machines used to form cylindrical workpieces. The machining process will determine the surface roughness at a certain level, this study was conducted to determine the surface roughness value of the workpiece, after turning it using a variation of tool angle 60?, 70?, 80? and engine rotation speed 200 rpm, 300 rpm, 1100 rpm with steel material ST37 and allumunium 6061. Based on the results of this study, the lowest workpiece surface roughness was found at 1100 rpm rotation speed with a large tool angle of 80? on the material type of carbon steel ST 37 at 1.373 ?m, while for the Allumunium 6061 material the lowest roughness was found at the speed 1100 rpm rotation and 60? tool angle with a roughness value of 1.1465 ?m.
