Abstract

A method of cutting a cut member out of an original sheet by means of thermal cutting and machining, and includes a hole-cutting process, a finishing process, and an outer periphery-cutting process. During the hole-cutting process, a hole is created in the original sheet by means of thermal cutting while leaving a machining allowance in addition to the finished size of the hole. During the finishing process, a cutting tool is inserted into the hole which has been created through the hole-cutting process, and the cutting tool is guided along the inner circumference of the hole so as to cut the thermally-cut end surface in order to machine the hole to the finished size. During the outer periphery-cutting process, the outer periphery of the cut member is cut by means of thermal cutting to take the cut member out of the original sheet.
