Experimental Investigations for the Prediction of Wear Zones on the Rake Face of Tungsten Carbide Inserts Under dry Machining Conditions

Dry machining tests on AISI 1040 steel using tungsten carbide inserts at various machining conditions are conducted to study the chip-tool interactions emphasizing on locating and characterization of various wear zones on the rake face of inserts. The edge chipping and crater wear zones are located and quantified for all the possible cases of chip tool interactions with different combinations of machining parameters. The generated data will enable the researchers and tool manufactures to contemplate on the specific wear zones rather than the complete rake face envisaging reducing the cost of production by having localised banded coated tools.
