<p>One element is taken from a machined shape (S1). When the element is a straight line element, whether or not the distance D between the start point and the end point of the element in a direction orthogonal to the axis of rotation of the workpiece is equal to or greater than a preset value Ds is determined (S3). In addition, whether or not an angle A that the straight line element makes with the Z-axis is equal to or greater than a preset angle Aa is determined (S4). When the distance D is equal to or greater than the preset value Ds and the angle A is equal to or greater than the preset angle Aa, a program is created with the cutting direction reversed from the profile direction (S5).</p> |
