Multi-response optimization in drilling using Taguchi's quality loss function

The exit burr formation in drilling is influenced by cutting conditions and drill geometry. This paper presents the application of Taguchi’s analysis for simultaneous minimization of burr height and burr thickness. The approach of Taguchi design for multi-response optimization problem is based on loss function of the quality characteristics. In the present investigation, optimal values of cutting speed, feed, point angle and lip clearance angle are determined to minimize burr height and burr thickness during drilling. The potential of the proposed methodology is demonstrated through a case study of drilling process using AISI 316L stainless steel workpieces. IPC Code: B23B
