Sheet Bending Calculator Pro
Bend Allowance & Deduction
$2.99 · Designed for iPad. Not verified for macOS.
Calculate bend allowance, bend deduction and flat pattern plate size using K-Factor for accurate sheet metal bending and press brake fabrication.
Sheet Bending Calculator is a professional engineering and fabrication tool for calculating bend allowance, bend deduction, and flat pattern plate size for sheet metal bending applications.
Designed for sheet metal fabricators, press brake operators, mechanical engineers, workshop technicians, and manufacturing professionals, the app helps determine accurate flat dimensions before bending and forming.
By simplifying bend calculations and eliminating repetitive manual trigonometry and spreadsheets, Sheet Bending Calculator helps reduce material waste, minimize fabrication errors, and improve bending accuracy.
Available Calculations
• Bend Allowance (BA)
• Bend Deduction (BD)
• Flat Pattern Plate Size
Bend Allowance Calculator
Calculate bend allowance using the required bending parameters:
• Bend Angle
• Inside Bend Radius
• K-Factor
• Material Thickness
The calculated bend allowance can be used to determine the developed length required before bending.
Bend Deduction Calculator
Calculate bend deduction for sheet metal fabrication and use the result when determining the correct flat pattern dimensions before cutting and forming.
Flat Pattern Plate Size
Determine the required flat plate or sheet size before bending.
This helps fabricators prepare material accurately and reduce:
• Material Waste
• Cutting Errors
• Trial and Error
• Incorrect Measurements
• Fabrication Rework
K-Factor Based Calculation
The calculator uses K-Factor as an important input for determining bend allowance and developed sheet length. This allows users to adjust calculations according to their selected bending conditions and fabrication requirements.
