Effect of CNC End Milling Parameters on Cu–Al–Mn Ternary Shape Memory Alloys Using Taguchi Method

CNC milling is a common technique for material removal that is used to create components with complex shapes and features. The purpose of the experiment is to determine how the CNC milling variables would affect the milling of Cu–Al–Mn (CAM) shape memory alloys (SMAs). For the investigation, an orthogonal array (OA) of the Taguchi’s L9 was employed. The CNC milling process’s depth of cut, feed rate, and spindle speed were chosen as the milling machining factors to study how they affected the MRR and SR of the workpiece. The examined end outcomes identified the milling settings that were most effective. ANOVA revealed that, in comparison with other components, the feed rate had the greatest influence on surface finish. By choosing the machining settings as given by the S–N Ratio graph, the ideal value of MRR and SR with a superior surface polish may be produced. SEM was used to examine the surface texture of the Cu–Al–Mn (CAM) SMAs’ milled profile. © 2023, The Institution of Engineers (India).
