Abstract

The quality of production goods, especially milling on aluminum material, is considered good if it is characterized by good surface quality of the components and efficient (short) machining time. There are various factors that affect this. This study investigated the CNC milling machining parameters, namely depth of cut and step over, which were written as the influence of the number and direction of cuts on the surface quality and machining time of aluminum materials. The purpose was to obtain the appropriate parameters so that the machining process is more efficient and with the appropriate quality. The CNC milling used was CNC Dahlih with a 6mm diameter tool, feed rate of 460 mm/min, and rotational speed of 2800 RPM. The variables were vertical cutting direction (depth of cut 5mm) with variations in step over of 0.5 mm, 1 mm, and 2 mm, and horizontal cutting direction (step over 5mm) with variations in depth of cut of 0.5mm, 1mm, and 2mm. So that the number of cuts can be equalized to 4, 6, and 12 in the vertical and horizontal cutting directions. The results showed that the more cuts, the lower the surface roughness, but it increased the machining time.
