The Lathes are 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 workpiece Stainlees steel 410 steel. In the turning process
using variations of spindle rotation 110 rpm, 300 rpm, 410 rpm and depth of cut
0.1 mm, 0.3 mm, 0.5 mm. In the turning process using variations of spindle
rotation 110 rpm, 300 rpm, 410 rpm and depth of cut 0.1 mm, 0.3 mm, 0.5 mm.
Based on the results of this study, the lowest surface roughness values were found
at spindle rotation speed of 110 rpm and depth of cut of 0.3 mm in stainlees steel
410 material of 0.981µm
