Experimental Research on Damaged Layer of High Strength Alloys in Precision Cutting

Abstract:

In this paper, the effects of cutting parameters and tool geometry parameters on the damaged layer were investigated with precision cutting of high strength alloy experiments. The mechanical and thermal effects on microstructure of sub-surfaces in precision turning high strength alloy are studied with a scanning electron microscope (SEM) analysis. A thin disturbed or plastically deformed layer is distinguished by the presence of grains that are elongated and rotated in the direction of cutting. No significant heat affected layer and phase transformation is found below the machined surface in all the tests. It also implies that mechanical deformation plays a larger role during precision turning.
