The effect of crystallographic orientation on the shear zone formation in micromachining has been analysed with a single crystal cutting model. Based on the minimum shear strength criterion, a range of shear angle values is found to exist. The most likely shear plane is the one that has the most negative texture softening factor among the ones with the same minimum shear strength. Theoretical findings for the shear angle and cutting force variations compare well with published experimental data. The significance of the microplasticity analysis to the understanding of chip formation in micromachining is discussed.
