Influence of Dry-Wet Machining Conditions on Surface Roughness of 6082-T6 Aluminum Alloy in Milling Process

In present study the optimum processing conditions were detected by exploring the surface roughness of the 6082-T6 aluminum alloy during milling, depending on the feed per tooth (0.03, 0.05, 0.07, 0.09 mm/tooth), spindle speed (1000,1500, 2000, 2500 rpm) and cooling type (air, liquid) parameters. Experiments designed according to Taguchi’s L16 orthogonal array. With the help of Signal/Noise ratios, the appropriate levels of the parameters have been determined to reduce the surface roughness value to the smallest value. The optimized machining conditions for surface roughness were observed 0.03 mm/tooth of feed per tooth and 2500 rpm of spindle speed and cooling by liquid. Variance and regression analysis were also made in the study. It was obtained that feed per tooth was the dominant parameter on surface roughness according to the analysis results. As last step, confirmation tests were carried out to check the success of the study.
