Abstract
An investigation of orthogonal metal machining was carried out to characterize workpiece materials and to correlate the findings of shear stress, shear strain and strain rate under a wide range of cutting conditions to the induced surface integrity of the machined surface. Standard materials testing techniques are widely known and applied in the dynamic range of deformation, but results of such methods cannot be generalized to reflect the condition of a workpiece being machined. This work involves the study of the machined surface integrity in the form of residual stress, strain and subsurface energy for a wide range of conditions. An attempt was made to relate the surface integrity to the dynamic characterization of the workpiece materials. It was found that an increase in cutting speed or feed rate led to a decrease in the average shear strain. It was also found that the average shear stress was constant for different cutting conditions. It was concluded from this research that an increase in cutting speed or a decrease in feed rate will lead to improvements in the machined surface integrity and reduction in the machining energy consumption.
