Abstract

Turning is a machining process used to shape products by cutting a rotating workpiece with a sharp chisel. One of the problems that occurs in the turning process is the level of surface roughness that does not meet the specified specifications. Even though the dimensions are in, the final product is rejected because the surface is too rough. The level of surface roughness is determined by several factors, including cutting speed, rotation speed and cutting edge geometry. Lathe tool geometry consists of clearance angle, relief angle, rake angle, and back rake angle. This research aims to determine the effect of spindle rotation speed and tool angle on the level of roughness of the workpiece on a lathe. Spindle rotation speed 300 rpm and 600 rpm. The only change in the tool geometry is the clearance angle with angles of 10°, 20° and 30°. The workpiece material used is ST37. The chisel material used is High speed steel (HSS). Testing of the results of the turning process is carried out by comparing the surface roughness with a surface roughness comparator. Cutting speed is not changed. From the research results, the recommended angle is an angle of 10º with the surface roughness results obtained being N5.
