Summary
Accurate flat patterns require correct k-factor and bend deduction. This tutorial shows measurement techniques and DFM for bend sequences.
1K-factor basics
Neutral axis shifts with tooling and material — use shop tables or test coupons.
2Bend sequence
Plan bends to avoid collision with tooling and previous flanges.
3Relief cuts
Add reliefs at tight corners to prevent tearing and spring-back issues.
Key points
- Validate k-factor with samples
- Plan bend order early
- Reliefs on tight corners
