Abstract

The purpose of this research is to see the effect of slope of incision angle chisel through Tool Post to roughness of surface of object. The method used is a lathe ST 37, with 0.5 mm cutting depth, with side angle cutting angle by tilting the Post Tool, ie: 10˚ tilted to the left, 10˚ tilted right, 0˚ (perpendicular), 5˚ tilted right, and 5˚ tilted left. Feeding (constant feeding) is: 0.281 mm / rotation, main cutting corner of chisel 80˚ and cutting speed = 740 rpm. Then the workpiece measured the surface roughness by using Surface Tester Mitutoyo SJ-201P. The result showed that, the smallest surface roughness rate achieved was (ΣRap) = 7, 42 μm with N9 surface roughness class with the Post Tool angle 5 ° to the left. While the largest surface roughness rate achieved is (ΣRap) = 13, 76 μm with the surface roughness class N11 with the tool angle post 10 ° to the right. The value of the roughness level achieved is between N9 - N11.
