Tools
Free sheet metal engineering tools.
Calculators for the numbers that come up before a part ever reaches the floor — bend geometry, flat-pattern length, and press brake tonnage. Every formula is shown on the page, every preset is labeled as typical, and every result is a planning estimate we verify with real tooling once you send us the part.
Forming
Bend Allowance, Bend Deduction & K-Factor Calculator
Live bend allowance, setback, bend deduction, and flat-pattern length, plus K-factor presets and a 90° reference table across common mild-steel gauges.
Open calculator
Forming
Press Brake Tonnage Calculator
Required tonnage for air bending by material, thickness, and die opening — tons per foot, total tons, and a mild-steel reference chart.

This list will grow — more free engineering calculators for sheet metal design are on the way.
