MACHINING SHEET, ITS MANUFACTURING METHOD, ABRASIVE SHEET, AND MANUFACTURING DEVICE OF MACHINING SHEET

摘要

PROBLEM TO BE SOLVED: To efficiently provide a machining sheet stuck to a curved face of a machining tool for grinding and polishing work. SOLUTION: The machining sheet is stuck to a grinding/polishing tool having a curvature so as to be used for a grinding/machining method in which a workpiece is pressed onto the machining sheet so as to be ground/polished. In formation of the machining sheet, notches are cut in a flat sheet so that a curved line matching the curvature is formed, so that the cut curved line of the machining sheet is conditioned so as to be numerically controlled.
