For what you are doing......If you compensate for the spring-back at initial forming, I can not imagine it moving that much after you apply a "set" to the material. We form a lot of metal parts at my current job, and do no additional processing other than the forming operation. I think it mostly depends on what level of tolerance you are working to. From the looks of it, you have (4) FHCS to pull it into shape when you install it. That should be enough to address any slight deviation in contour between parts. |
