The fact thu the surface obtained in finish-turning are worse than is expected on theoretical grounds, is disconcerting. These results are due to the formation of groove wear in the clearance face of tool. As described in this paper quantative relations between surface roughness and groove wear are studied. Following results are attained. 1) Development of groove wear with tool travel is greatly affected by chip flow direction and feed. 2) Maximum depth of groove can be showed as function of chip flow angle and feed. 3) Formation of surface roughness is affected by groove wear, that is, the fact that grooves transfer to surface of workpiece is observed. 4) Depth of groove is made shallower when end-cutting-edge angle, feed and angle between chip flow direction and rotatory axis of workpiece are selected smaller.
