常见问题 (FAQ)
What is the minimum bend radius (R)?
The minimum inside bend radius that prevents cracking when bending sheet metal. Varies by material, thickness, and grain direction. Typical values: mild steel (SPCC) 0–0.5t, SUS304 0.5–1.0t, aluminum A5052 1.0–1.5t.
What is the relationship between bend direction and rolling direction?
Bending perpendicular to the rolling direction (grain) reduces crack risk. Bending parallel to the grain requires a larger minimum R. It is best practice to annotate both bend lines and rolling direction on drawings.
