Estimating the term…
A profile processing method and a processing machine therefor which can obtain a good finish surface accuracy in all the carving surfaces and curb the decrease in tool's life are provided. More specifically, an end mill is first moved along an outermost side of an annular groove in carving the annular groove to a work. Consequently, the end mill is gradually moved to inside to be moved and carve along the annular groove. When the outermost side of the annular groove is carved, the movement path of the end mill is selected so that the outermost side is down-cut (counterclockwise in FIG. 5). When further inner side is carved, the movement path of the end mill is selected so that the direction of the relative movement path is opposite to the direction of the relative movement path when the outermost side is carved, in other words, the carved surfaces are down-cut by the end mill.
