    Air Bending Chart Lasercut Capacity

    Uploaded by

    Steve Bottomley
    The document provides a chart with calculations for the tonnage of material required to air bend metal pieces of varying thickness, inner radius, and V-width to a tensile strength of 42kg/mm2. The chart lists the minimum flange length and bending force for different thickness, radius, and V-width combinations. Notes provide guidance for adjusting the tonnage calculations for other material strengths like stainless steel or aluminum.

    Tonnes (ton) required for air bending material of a tensile strength = 42kg/mm2 one metre long, with a thickness

    (T), and inner material radius (R).


    AIR BENDING CAPACITY CHART
    Minimum dimension of flange (a) and V width (v) are also shown.
    Calculations are based on tensile strength of 42kg/mm2 - mild steel. To calculate 60kg/mm2 - stainless steel - increase tonnage by 40% To calculate 30kg/mm2 - aluminium - decrease tonnage by 30%.
