| Abstract | ||
| This research aims to find the optimal conditions affecting the surface roughness when copper is turned. In this work the Taguchi method is used to optimize the cutting parameters. The parameters considered here are: spindle speed, feed rate, and the tool nose radius while the depth of cut has been fixed during the experiments. The tool used for conducting the experiment is High Speed Steel (HSS). Once the surface roughness is measured, the quality characteristic “smaller is the better” is applied to calculate the signal to noise ratio S/N for each experiment. Also, by using ANOVA output, the factor that has more significant in the process has been determined depending on its percentage of contribution. The results showed that the optimum combination of levels of the parameters were (3-1-1) that are corresponding to spindle speed (1120 rpm), feed rate (0.065 mm/rev), and tool nose radius (4 mm). The significant factor that has maximum contribution according to ANOVA results is the spindle speed with 58.581% followed by feed rate and tool nose radius respectively. | ||
