Abstract
This study aims to optimize cutting parameters in the CNC milling process for manufacturing prosthetic foot molds made of AISI 1020 material in order to achieve machining time efficiency and surface quality that meets standards. Three main parameters were tested, including Stepover, feed rate, and depth of cut, each at three levels. The experimental design uses the Taguchi method with Orthogonal Array L27, while the analysis is carried out through Signal-to-Noise (S/N) Ratio and Analysis of Variance (ANOVA) to assess the effect of each parameter on two responses, namely machining time (Mastercam simulation) and surface roughness (experimental test). The results of the study indicate that all parameters have a significant effect on machining time, with feed rate being the dominant factor in accelerating the process with an optimal combination of 0.45 mm Stepover, 800 mm/min feed rate, and 0.4 mm depth of cut. In terms of surface roughness response, the optimal combination was obtained at a Stepover of 0.15 mm, a feed rate of 300 mm/min, and a depth of cut of 0.2 mm with an average Ra value of 1.101 µm. Furthermore, multi-response optimization using the Desirability Function produced the best parameter combination at a Stepover of 0.30 mm, feed rate of 500 mm/min, and depth of cut of 0.30 mm, which gave an overall desirability value of 0.73940. This combination produces a surface roughness of 2,368 µm and more efficient machining time, namely 13,221 hours for the upper part and 12,197 hours for the lower part of the mold. Overall, this study confirms that proper cutting parameter settings can improve process efficiency and surface quality in prosthetic mold manufacturing. Keywords: CNC Milling, Optimization, Surface Roughness, Machining Time, Desirability Function.
