Abstract
In manufacturing industries not quit off from quality that planned by consumer. Almost all manufacturing industries not quit off from machining process that be nub of the manufacturing process. Product geometry and variation accuracy need human resources to be more developed. Surface roughness is one of factor that determines product quality from a turning process. A research that analyzing effect of tool auxiliary cutting edge angle (kr’), cutting speed (v) and feeding movement (f) can be use to predicts tool age. Turning process on AISI 1020 low steel carbon type which have been made with tool auxiliary cutting edge angle (kr’) variation, i.e : kr’1 = 20, kr’2 = 40, kr’3 = 60, kr’4 = 80, kr’5 = 100, kr’6 = 120, kr’7 = 140, and cutting speed (v), i.e: v1 = 13.79 m/min, v2 = 25.35 m/min, v2 = 31.69 m/min. Analysis of surface roughness data obtained that tool auxiliary cutting edge angle (kr’) has the longest tool age is 60 with cutting speed (v) is 25.35 m/min, i.e 2.21 µm, whereas the highest surface roughness value achieved 3.73 µm with tool auxiliary cutting edge angle (kr’) is 140 and cutting speed (v) 13.79 m/min. Then, the highest tool age obtained in kr’ = 60 with v = 13.79 m/min,i.e: 793.02 seconds, whereas the lowest tool age obtained in kr’ = 160 with v = 31.69 m/min,i.e: 81.12 seconds. The data give a conclusion that the tool auxiliary cutting edge angle (kr’) affecting the value of surface roughness.
