Whirling, in which a rotating workpiece is machined by rotating tools around the workpiece with an eccentricity between the centers of the workpiece and the tool rotations, has been generally performed in threading. The whiling mechanism is applied to polygon machinings in this study. In proposed machining, the ratio of workpiece rotation rate to tool rotation rate is set to be n : 1 to machine n polygon prism. An analytical model was established to control the machining shape. The cutting tests, then, were conducted to verify the presented machining with the analytical model. Machining examples of triangular, square and pentagonal prisms were demonstrated in whirling. The effect of the tool rotation radius on the curvature of the workpiece surface is discussed in measurement of the machined shapes.
