Optimization research on aluminum-nickel alloy milling using the Taguchi method

The study aimed to explore the machining parameters of general milling and used the Taguchi method to obtain the optimal parameter combination and contribution value of surface roughness. Essential process parameters were identified, including spindle speed, feed rate, depth of cut, and tool diameter. Then, in the experiment, the spindle speed parameters were set to 2000rpm, 2500rpm, and 3000rpm. The feed speed parameters were set to 400mm/min, 500mm/min, and 600mm/min. The milling depth parameters were set to 0.2mm, 0.4mm, and 0.6mm. Based on the experimental results, the following conclusions were drawn. The optimization factors for surface roughness in general milling were spindle speed A2 (2500rpm), feed speed B2 (500mm/min), cutting depth C2 (0.4mm), and tool diameter D3 (4mm). After individual quality optimization analysis and verification experiments, the optimized surface roughness measurement value was Ra 0.23μm, which was an increase of 56.52% compared to the average best value of Ra 0.36μm in 9 sets of tests.
