Brakewright Metal Calculator

Brakewright is a calculator for press brake operators, fabricators, duct and enclosure shops, programmers and students. It works like a hardware calculator: a steel-blue chassis, real keys and a clear LCD, with each answer labelled so you know what you are reading.

BENDS
• Bend allowance, outside setback and bend deduction from thickness, inside radius, bend angle and K-factor
• Bend angle or included angle, whichever your drawing gives

FLAT BLANKS
• Add outside flange lengths and see the flat blank grow, one bend deduction per bend
• Bends at different angles in one part
• Closed hems (about 0.43 × T) and open hems

K-FACTOR
• Typical 0.44 when none is set, or your own
• Solve K from a known bend allowance, a bend deduction or a measured test bend

SHEET GAUGES
• Gauge to thickness for mild steel, galvanized, stainless and aluminium, computed from the public gauge definitions

PRESS BRAKE
• Recommended V-die opening (8 × T), air-bend radius and minimum flange
• Air-bend force in tons per foot or tonnes per metre, and the total for the bend length, with material factors for mild steel, galvanized, stainless and aluminium

WORKS THE WAY YOU DO
• Inches or millimetres; decimals to four places in inches, two in millimetres
• A results strip shows every solved value at once
• 10 memories, a tape of your calculations, reference tables (gauges, air bending, material factors) and a key guide
• Export a job strip: the tape with inputs, stamped and ready to attach to a lift plan, sign-off or take-off, as text or PDF

Questions or feedback: support@wrightcalc.app

Die, radius and force figures are rules of thumb. Confirm tonnage against the press brake's rated capacity and the die maker's chart before bending, and verify every result with a test bend. The developer accepts no liability for loss or damage arising from use.
