However, you are going to need to get the k-factor numbers from your vendor. k-factor is best calculated by doing bends and measuring the results on a simple test piece for each material type, thickness, and bend radius. So hopefully your vendor can supply you with their bend radii for their tooling and the needed k-factors.&nbsp;</P> Mon, 29 Jul 2019 21:04:58 GMT kellings 2019-07-29T21:04:58Z Sheet metal bend reduction https://forums.autodesk.com/t5/fusion-manufacture-forum/sheet-metal-bend-reduction/m-p/8936765#M102304 <P>I'm designing a couple of parts made of 2mm aluminium.
