Online Monitoring of Metal cutting of Inconel600 with Al2O3 coated carbide tools

Abstract The present research work focuses on experimental investigation of the effect of machining parameters on temperature distribution on work piece, cutting forces and surface roughness of Inconel 600 using Tungsten carbide tool with Al 2 O 3 coating and without coating. The measurement of interface zone temperatures on work piece was performed using infrared thermal camera. The cutting, feed, thrust forces were measured using Kristler dynamometer. The surface roughness was measured by using Taylor Hobson surface roughness tester. The experimental work was initially carried with Full Factorial Design to evaluate the effect of machining parameters on the temperature distribution on workpiece,cutting forces and surface roughness with uncoated tools.Using this data optimized machining parameters were computed using ANOVA.In view of comparison of performance with Al 2 O 3 coated tool bits, L9 orthogonal array of DOE using Al 2 O 3 coated tools was done. The reduction in cutting forces, interface temperatures and surface roughness was more with the use of coated carbide tool when compared with uncoated tool.
