## Abstract
One of the most factors that affect the quality of machining results is the machinability of materials. Machinability can affect the accuracy of dimension of the machining product, especially in producing small products. This study has purpose to obtain the circularity value and surface morphology of specimen as indicator of machinability of alloys Al 6020 by using face turning method in the range sub-millimeter. The effects of spindle speed and feed on circularity and surface morphology are the subject of the study. Three variations of spindle speed (440 rpm, 740 rpm and 1500 rpm) and six variations of feed (0.05 mm/rev, 0.1 mm/rev, 0.2 mm/rev, 0.3 mm/rev, 0.5 mm/rev and 1 mm/rev) were used. The circularity was calculated by image processing software and surface morphological was observed using SEM and optical microscope. Results show that the better circularity was found on smallest and largest feed for each spindle speed. The surface morphology shows some burr defect and also scatter.
