PROBLEM TO BE SOLVED: To perform curve interpolation by obtaining a curve settled within the tolerance of a target curve set as the target of a command point sequence, and obtaining a curve closer to the target curve. SOLUTION: Interpolation points Q are obtained between the respective command point sequences P, and the interpolation points Q are made command shape points. The command shape points Q are within the tolerance width w of the target curve formed with the command point sequences P. The respective points of the command shape points Q are sequentially made noticed points, and an approximate curve is sequentially formed from a plurality of command shape points in front and in the rear of the noticed points. The noticed command shape points are moved to the approximate curve and made correction command points. A curve is formed in order from the correction command points, and curve interpolation of the curve is performed. Since the command shape points (interpolation points) Q exist at the center part of the tolerance width w compared to the command point sequences P, the approximate curve and the correction command points are at the center part of the tolerance width w, and the formed curve is settled within the tolerance width w to obtain the smooth curve.
