We are messing around with unfolding sheet metal parts. One problem we are encountering is that the unfolded parts are not workable. The stretch that happen during bending is different from what Solidworks calculates. we have used different bend allowance table and k facters ... but still the bend allowance/ stretch are off. Usually when we calculate stretch at the shop for stainless steel we use 1.6 X thickness and that give us a very accurate stretch. Where can we find info on how to get Solidworks to unfold with the correct stretch/bend allowance?
