Abstract

This paper presents an analysis of the chip characteristics and surface roughness in dry machining of aluminium alloys. The experiments carried out consisted of different cutting condition models based on combination of cutting speed, feed rate and depth of cut as the parameters of cutting process. The design of cutting parameters models was base on design of experiment response surface methodology use of Minitab Software. The results show that, the chips produced in turning of LM6 and AA7050 aluminium alloy was found different chip shape for the similar of cutting condition model. Surface roughness values of AA7050 alloy was found to be lower as compared to surface roughness values of LM6 alloy in the similar of cutting condition model. The values of surface roughness also has affected by combination of cutting parameter when machining of aluminium alloys. The good quality of surface roughness was found in the cutting model no. 1 (v = 100 m min-1, f = 0.05 mm rev-1 and ap = 1 mm) when turning of AA7050 aluminium alloys, and at the cutting model no. 6 (v = 250 m min-1, f = 0.125 mm rev-1 and ap = 0.5 mm) when turning of LM6 aluminium alloys.
