Experimental investigation on the cutting mechanism of oxygen free copper in cutting speeds ranging from 1 m/s to 210 m/s
The orthogonal cutting tests of oxygen free copper with a cutting speed of from 1 m/s to 210 m/s were performed.The effect of the high-speed cutting on the improvement over the quality of the machined surface,which was evaluated by the thickness of the plastic flow layer and the surface roughness,was examined.By employing the simple shear plane model,the cutting mechanism was analyzed.The results were compared with the results for cutting of aluminum alloy obtained previously.For oxygen free copper,the resultant cutting force does not increase in high-speed cutting.However,the friction angle on the tool-chip interface rises clearly in high-speed cutting.This paper discusses the reason for the increase in the friction angle at the tool-chip interface by investigating the stress and temperature fields on the shear plane and the tool-chip interface.
