Abstract

In this study, optimum
machining conditions were determined by investigating the surface roughness of
the 7075-T6 aluminum alloy milling, depending on the spindle speed (rpm), feed
per tooth (Fz-mm/tooth) and the cooling type parameters. Taguchi experiment
design method was used to save time and cost. Experiments were based on the
Taguchi L16 orthogonal array and signal/noise (S/N) ratios were used in the
evaluation of the test results. Optimum surface roughness values were
determined with Taguchi optimization. In addition, variance analysis and
regression analysis were performed. Confirmation tests were conducted to verify
the work. As a result of the confirmation tests, it was found that the surface
roughness optimization in the milling of the 7075-T6 aluminium alloy was
successfully applied.
