Optimization of Surface Roughness in Dry Turning of Brass

Abstract:

This study aimed to investigate the effect of cutting speed, feed and depth of cut on the arithmetic mean surface roughness (Ra). The optimal cutting condition in dry turning brass with carbide cutting tool was also recommended. The experimentation was designed by using Taguchi Method (L₉). Three investigated factors with 3-level each were cutting speed (42, 68 and 110 m/min), feed (0.05, 0.1 and 0.15 mm/rev), and depth of cut (0.15, 0.25 and 0.5 mm). The results indicated that speed and feed were significantly affected at average surface roughness. The optimal cutting conditions were cutting speed at 68 m/min, feed at 0.05 mm/rev and depth of cut at 0.15 mm.
