The effect of crystallographic orientations of the workpiece material on cutting deformation and machined surface quality in diamond cutting of single crystal copper is studied. The experimental results show that the shear angle, the cutting force and the machined surface roughness vary considerably with the crystallographic cutting direction. The trend in the variation of shear angles and cutting forces is analyzed based on a microplasticity model of chip formation. Analytical results compare well with the experimental data.
