Multi-objective optimisation for the micro-end milling process using Taguchi quality loss function

Highly accurate miniaturised components are increasingly in demand for various industries such as aerospace, biomedical, electronics, environmental, communications and automotive. Micro-machining is the process of manufacturing the components by using the miniaturised technologies. In this research work, the Taguchi quality loss function analysis is used to examine and explains the influences of three process parameters (spindle speed, feed rate and depth of cut) on the output responses such as MRR and Ra in micro-end milling process. Also, this approach is used for the optimisation of multiple responses in micro-end milling operation to achieve maximum metal removal rate (MRR) and minimum surface roughness (Ra). Further, the optimised machining parameters were determined considering the multiple response objective using Taguchi MSNR. From the experimental result, it was concluded that the Taguchi technique is suitable for the optimisation of multi-response problem.
