Description of the Related Art Currently, the applications of small parts using functional materials such as silicon (Si), lithium niobate (LiNbO 3 ) and lithium tantalate (LiTbO 3 ) are expanding. In order to cut (slice) such a brittle material into a thin plate, conventionally, a cutting method in which a donut-shaped diamond cutter, a wire (piano wire) or a steel cutter is combined with an abrasive such as silicon carbide or aluminum oxide is used. Although used, these conventional cutting methods fix the brittle material to the stage, and the stage moves linearly toward the cutter, so that the cutting surface is flat.
