Abstract: This paper presents application of Taguchi optimization method for simultaneous minimization of burr height and burr thickness influenced by cutting conditions and drill geometry. The approach of Taguchi design for multi-objective optimization problem is based on the introduction of a new concept of fitness function for each trial of orthogonal array. The fitness function is derived through mapping the objective functions of the drill optimization problem. In present work, optimal values of cutting speed, feed, point angle and lip clearance angle are determined for a selected drill diam to minimize burr height and burr thickness during drilling of AISI 316L stainless steel workpieces. The effectiveness of proposed method is demonstrated through simulation results and experimental verifications.
