Shape memory alloys (SMAs) based on copper have higher transformation temperatures throughout a wide range of compositions, as well as excellent ductility, which results in superior machinability. The main goal of this work is to determine the CNC turning machining parameters for Cu-Al-Mn SMAs made by the induction melting procedure in an induction furnace. Taguchi’s DOE was used to choose the L9 orthogonal array (OA). A performance analysis, comprising an experimental study of Surface Roughness (Ra) and Material Removal Rate (MRR), was conducted using Cu-Al-Mn SMAs’ turning parameters. The objective of this study is to determine the effects of feed rate, depth of cut and cutting speed on MRR and Ra. Using ANOVA, it was possible to pinpoint the main cause of both MRR and Ra. Based on the S/N curve, the optimal Cu-Al-Mn SMA parameter configuration to optimise MRR and reduce Ra was chosen. The Taguchi technique has been used to improve the CNC turning of Cu-Al-Mn SMAs that were machined using tungsten carbide tip tools. |
