ABSTRACT: Turning clearance angle is changed
machining characteristics. In this study, the experiments start from choosing
two workpiece materials that are machine structural carbon steel, chrome-molyb-
denum steel. Then, the experiments show specifically how features of selected
materials changed when they were processed with machining operation. In order
to find the surface roughness of workpiece materials, the workpiece materials
which have higher tensile strength showed much better value of surface
roughness in a surface roughness tester. Moreover, process feed rate was
compared between 0.05 mm/rev and 0.10 mm/rev. When process feed rate was 0.05
mm/rev, surface roughness has superior results without reference to the quality
of the materials.
