PROBLEM TO BE SOLVED: To overcome the problem wherein, when a cutting member comprising materials with thickness and high hardness, such as rubber plates or acrylic boards is cut into a circle in a cutting plotter, the starting point and end point of cutting trajectory are not matched, resulting from that the rotary drive of a cutter blade being unable to follow the movement in a two-dimensional direction of the cutting part, since the cutting resistance of the materials is large. SOLUTION: The displacement between the starting point and end point, caused, when actually cutting a cutting medium by using the data of a circle to be cut, is set as a correction amount. On the basis of the data of the circle to be cut, helical form data are created, such that the cutting end point of the circle becomes a position spaced apart by the correction amount in the center direction of the circle more than the cutting start point, and the cutting is made on the basis of the helical form data.
