Abstract
A milling cutter is composed of a tool body having an approximately cylindrical or disk-like shape and a plurality of edge portions provided on at least an outer peripheral portion of one end of the tool body at predetermined intervals along a circumferential direction. The edge portion has a major cutting edge and a minor cutting edge that perform an operation of cutting a workpiece, the major cutting edge is positioned outside the minor cutting edge in a radial direction, and the minor cutting edge has a cutting edge angle that is an angle with respect to a plane orthogonal to a center axis of the tool body and set so as to be an elevation angle open outward in the radial direction. When surface machining is performed on a workpiece with the milling cutter, a high degree of machined surface accuracy equivalent to that obtained by grinding is obtained.
