1. Check the material and plate thickness to the tolerance of plate thickness.
2. For special angles, the radius of the bending Angle should be expanded according to the trial folding.
3. The places prone to mistakes should be highlighted.
4. Enlarged pictures should be added for places with larger sizes.
5. The place to be sprayed shall be indicated.
6.The way of expansion should be reasonable, and it should be convenient to save materials and processability.
7. Reasonable selection of gap and edge wrapping method, T=2.0 gap 0.2, T=2-3 gap 0.5, edge wrapping method using long edge wrapping short edge.
8. Reasonable consideration of tolerance dimensions: negative difference to the end, positive difference to half;
Hole shape size: positive difference to the end, negative difference to half.
9. Extraction, riveting, tearing, punching convex point, and other location methods.
