Design precision can be critical for many sheet metal fabricated parts. The difference of a very small margin can result in something that fails, can’t be assembled, or simply doesn’t meet your expectations.
In another article of the Sheet Metal Fabrication Guide, we discuss the importance of tolerances for both laser cutting and bending.
A simple error in something like the size or spacing of a hole can have a big impact on the manufacturability of a part.
Please review this article (link above) with your design team so you’re confident you’ve met all the tolerance requirements before you send your drawings to your fabricator.
