- Further reading：meviy: range of processing limits
- The values on this page are the limits above (measured from the outer edge of the hole) plus the hole radius, so that they are measured from the hole centre. They are not a direct copy of the source.
- a is the minimum distance from the hole centre to the sheet edge, b the minimum pitch between hole centres, and c the minimum distance from the hole centre to the bent edge.
- Note that meviy measures from where the chamfer or fillet begins, so a chamfered or filleted corner changes which dimension is checked.
- Actual manufacturing limits vary between suppliers. Check with your sheet metal fabricator for the values that apply to your parts.
