Press Brake Tonnage: How to Calculate Bending Force (Formula + Chart)
Press brake tonnage is calculated with a simple supplier-document formula: required tonnage (tons) = sheet thickness (mm) x 8 (fixed coefficient) x bend length (m), for steel sheet. Stainless steel is multiplied by 2 because its springback is large. Tonnage depends on three factors: material type, material thickness and bend length. This guide explains the […]
