The results of experimental study of ultraprecision orthogonal microdiamond cutting of single-crystal copper are presented. The orthogonal cutting tests were carried out on an ultraprecision fly-cutting machine at various nominal depths of cut from 3.0μm down to 0.01μm (10nm). The machinability in microcutting and the influence of crystal orientation on the microcutting process are discussed from the standpoints of chip formation, cutting force and surface integrity. It is confirmed that continuous chips are formed under all cutting conditions examined. The magnitude of the cutting force and the shear angle are substantially influenced by the crystal orientation at depths of cut of 1μm or more, while they are not notably influenced with depths of cut below 1μm.
