ABSTRACT:
A calculation method includes the steps of: setting a moving condition about the respective wire materials; regarding cross-sectional shapes of the wire materials as a plurality of circles; assuming a comprehensive circle containing the circles; defining a target circle which is slightly smaller than the comprehensive circle; searching for a destination position into which the circles excluding an insertion-tried circle is moved as farther as possible from the insertion-tried circle; inserting the insertion-tried circle into a space within the target circle; defining a new target circle that is slightly smaller than the present target circle when all the insertion-tried circle is inserted in the target circle, and returning to the searching step; repetitively performing the defining step, the searching step, the insertion step, and defining step of the new target circle for reducing the comprehensive circle; and determining information about positions of the comprehensive circle and the circles.
