Abstract:
A method for finishing a surface of a workpiece having a bottom and a slope continued from the bottom using a rotary tool, comprising the steps of:selecting a relative movement path of the rotary tool and the workpiece so that the slope and the bottom are always carved by down-cut; andcarving the bottom and the slope along the relative movement path;wherein in carving the slope the rotary tool and the workpiece are relatively moved so that the rotary tool is moved approximately parallel to a ridgeline between the slope and the bottom and so that the rotary tool is gradually moved to approach the ridgeline from a position remote therefrom, and wherein in carving the bottom the rotary tool and the workpiece are relatively moved so that the rotary tool is moved approximately parallel to a ridgeline between the slope and the bottom and so that the rotary tool is gradually moved to approach the ridgeline from a position remote therefrom.
