Accuracy & Economics of sheetmetal forming using reconfigurable tooling

• The accuracy of the sheetmetal formed depends the accuracy with which the discrete elements are positioned, the smoothening of surface of the discrete elements and springback (Fig. 6)
• It is possible to compensate for spring back and other size variations using techniques such as experimental determination of the deformation transfer function and FEA method [20]
•  Papazian et al [20] reports that a reduction to 1/8th and 1/3rd of the current tool fabrication cycle time and labour hour respectively is obtained
• Owodunni et al [17], showed  that it is possible to achieve great savings in the capital investment to the extent that the cost of a reconfigurable tool can be comparable to that of a conventional die
