Comparative Study of Wear Patterns of both Coated and Uncoated Tool Inserts in High Speed Turning of EN36 Steel

Abstract

The main purpose of the study is to test the applicability of different cutting tools in producing tool-making equipment and to lay emphasis on the mechanisms present in the high-speed-cutting. The study would be of great benefit in the design and the selection of tool materials and also to control tool wear. The machining on EN36 steel was performed on CNC Turning Machine and design of experiments were made by using Taguchi method. The tool flank wear patterns were observed by tool maker’s microscope and comparative study is made for both coated and uncoated tools inserts. The comparison performed identifies the best validated cutting tool having improved performance among coated and uncoated inserts and gives optimum parameters in order to reduce the cutting forces for all cutting speeds. These values obtained shows coated tool inserts outperformed over uncoated at higher cutting speeds.
