The result will be gaps in your blade that could ultimately cause it to fail prematurely.Ĭ) change your design to something manufacturable for traditional stamping process. Remember ALL sheet metal stamping builds mechanical stress into the material that WILL be released in spring-back. Such an overlapping helix as yours creates a continual undercut that simply can't be tooled in the real world using conventional sheet stamping methods.ī) "segment, stamp and weld" - invites massive problems not only in part complexity but also manufacturability. We discussed this last week as regards Pro/ENGINEER, but the qualification needs to be that the part is manufacturable to start with. The basic problem is that your shape is simply not manufacturable in the real world without first breaking it up into tiny parts.
