Calculation Scope

Conventional single-bend air forming. It is not intended for bottom bending, coining, hemming, offsets, radius tooling or multiple bends in one stroke.

Distributed Tonnage

Confirm total machine capacity and the tons-per-foot or kN-per-meter limits of the ram, bed, punch, die, clamps, adapters and holders.

Material Variation

Actual force changes with tensile strength, grain direction, tooling geometry, friction, radius requirements and machine condition.
