We have been manufacturing press brakes for nearly 20 years, and we are able to customize them according to the actual needs of our customers, regardless of their needs. The formulas in the books and in the web calculator I linked are approximations and do not account for chord length but assumes the bend is circular. Our conversions provide a quick and easy way to convert between Angle units. Rather than rely upon bend radius to be your guide, rely on bend diameter. R i Internal radius of bend F Bending force necessary to make the bend. The cable bending radius is the minimum radius a cable can be bent without damaging it. A Sharp bend will always be less than a Minimum bend radius but, a Minimum. Minimum Bending Radius Calculator. 36 /11kV suitable for power networks in fixed installations outdoors in cable ducts or directly into the ground. The allowable bend radius is defined as the acceptable degree of deflection or curvature that a product pipe, drill pipe, mud motor or wireline system can safely tolerate without risk of significant damage to the component in question. Say you’re bending soft, 13-KSI aluminum with a 0. Kerf Spacing. Considering that the radius is the only thing (aside from material thickness) that SW uses to calculate your bend parameter, you will have to use a radius that refers to your bending style for that material and process. For example, a cable having a maximum SWBP of 300 lb/ft that is being pulled around a bend having a radius of 2 ft should have no more than 300 lb/ft x 2 ft or 600 lb tension applied to it as the cable exits the bend. If the distance between bends is not greater than the length of each bent segment, select a lesser number of bends to make, and/or a different centerline radius.
