Sheet metal fabrication
How do I compensate for springback in sheet metal bending?
Answer
Formed edges and profiles that keep fit in assembly. Springback management Tooling and program compensation confirmed on first pieces. Sequenced forming Bending planned with cutting and finishing so tolerances survive. Bending Design Review Bend radius vs thickness Radius, material temper and thickness set the practical limit;

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
