Machining Studies of EN-353 Steel Using Taguchi Technique by Turning Operation

This paper presents an optimization method of the cutting parameters like cutting speed, feed rate and depth of cut in dry turning of EN-353 steel in order to study the performance of coated and uncoated ceramic cutting tool inserts. Experiments are designed and conducted based on Taguchi's L9 orthogonal array carried out under dry cutting conditions. The force measured are feed force, tangential force and to achieve minimum flank wear measured by optical tool wear microscope. The depth of cut was identified as the most influential process parameters in the responses of both feed force and tangential force. The cutting speed has a significant contribution for flank wear. Finally, the feed rate was identified as the most influential process parameter in the responses of both feed force and tangential force. Keywords—Feed force; tangential force; flank
