The Hole Was Correct. The Bent Part Was Not.

We once had a sheet metal part where the laser-cut profile matched the drawing, but the final assembly still had alignment issues.

The problem was not cutting accuracy.

After bending, springback and material movement changed the relationship between the hole and the formed features.

This is something easy to miss when reviewing a flat pattern.

In sheet metal, a hole is not only a 2D location. Its final position depends on how the entire part behaves during forming.

The design looked right in CAD, but manufacturing revealed another factor.

How do you usually handle critical holes near bend lines?
