Abstract: A control device that controls polygon turning to simultaneously rotate a workpiece and a tool and form a polygon on a surface of the workpiece inputs information on misalignment in a rotation direction of a cutting tool T attached to a tool body, generates adjustment pulses to correct the misalignment in the rotation direction of the cutting tool T, and generates a rotation command for rotating, at a predetermined angular velocity, a tool axis used for performing polygon turning. The control device then superimposes the generated adjustment pulses on the generated rotation command in idle running of the tool, corrects the misalignment in the rotation direction of the cutting tool T, and thereby improves the precision of the polygon turning.

Abstract: A control device that controls polygon turning to simultaneously rotate a workpiece and a tool and form a polygon on a surface of the workpiece acquires information on misalignment in the radial direction of a cutting tool attached to a tool body and generates pluses to correct the misalignment in the radial direction of the cutting tool. Furthermore, the control device outputs the pulses to an X-axis servo motor and moves a tool in the opposite direction to the misalignment in the radial direction of the cutting tool. Accordingly, the misalignment in the radial direction of the cutting tool is corrected, and thereby the precision of the polygon turning is improved.

Abstract: An oscillation component a×sin(M?t) (M is the number of sides) that becomes the maximum when a tool cuts the center of a machining surface is superimposed on a reference angular velocity 2? of the tool. The angular velocity of a tool shaft becomes higher as the tool shaft comes close to the center of the machining surface and becomes the maximum when the tool shaft is at the center of the machining surface. It is possible to adjust the flatness of the machining surface by adjusting an adjustment parameter a of the oscillation component a×sin(M?t).
