Abstract
A surface finishing method and a machine therefor, in which good finish accuracy can be obtained in all carving surfaces and deterioration of tool's life can be prevented. When a surface of a concave portion formed on a workpiece is carved, an end mill is first revolved along an outermost side of a slope, and is moved toward inside and revolved along a circumferential direction. When a surface of the slope is carved, a movement path of the end mill is selected so that the surface of the slope is down-cut. When a bottom is carved, the end mill is moved from inside to outside, in other words, the movement path is selected so that a surface of the bottom is down-cut.
