METHOD AND SYSTEM FOR BENDING

摘要

Three-dimensional stereoscopic diagram creating means (9) creates a three-dimensional stereoscopic diagram based on graphic information of a product and major dimension display means displays a major dimension, tolerance and the like with respect to the three-dimensional stereoscopic diagram. On the other hand, test piece display means (15) displays a test piece TP manufactured preliminarily of the same material as material used for producing the product and carries out trial bending on this test piece. A bending angle after a bending load is removed is measured by a bending angle measuring device (25). A spring back amount setting means (17) calculates a spring back amount from a difference in bending angle between before and after the load is removed. Object stroke calculating means (19) calculates an object D value relative to the object bending angle considering the obtained spring back amount and carries out actual bending.
