Experimental Research on Surface Residual Stress of Quenched GCr15 Steel in Ultrasonic Aided Turning

Abstract:

Surface residual stress has become one of the important indexes measuring surface integrity in hard turning of precision parts. The type of surface residual stress and the influence rules of cutting parameters on surface residual stress in hard turning of GCr15 steel are studied in this paper. Research results show that no matter in common or ultrasonic turning, tangential surface residual compressive stress can be found in machined surface. The effect of cutting speed on the residual compressive stress is the greatest, the effect of feed rate takes the second place and the effect of depth of cut is minimal. The conclusions have provided experimental basis for enhancing the surface integrity of quenched GCr15 steel precision parts.
