Engineering Tools
Free browser-based calculators and reference charts for sheet metal bending, power transmission, part weight, machining, and material planning. Built for engineers, makers, students, and FRC teams—with no software download.
Bend Allowance and Bend Deduction Calculator
Use measured Fabworks material and tooling values, or enter generic inputs to calculate bend allowance, outside setback, and bend deduction.
Open calculator
3D Part Weight Calculator
Upload a STEP file to calculate its modeled solid volume and weight from a Fabworks material, engineering material, or custom density—all in your browser.
Open calculator
Material Weight Calculator
Calculate flat material, pipe, conduit, and tube weight from custom dimensions or common construction and electrical profile sizes.
Open calculator
Motor & Gear Ratio Calculator
Calculate motor power and ideal ratio from linear or angular acceleration, or model output RPM and torque directly. Optional FRC mode adds motor presets and a linked COTS gear catalog.
Open calculator
Chain Sprocket Generator
Create a laser-cuttable plate sprocket STEP for common ANSI roller chains, calculate its dimensions and chain speed, then order it from Fabworks.
Open calculator
Bend Radius Calculator
Estimate finished inside and outside bend radius from Fabworks material, thickness, tooling, and bend angle.
Open calculator
Minimum Flange Calculator
Find the minimum flange length and approximate distortion zone for Fabworks press-brake tooling.
Open calculator
Minimum Joggle Calculator
Check the bend angle and spacing needed for a joggle made with Fabworks standard press-brake tooling.
Open calculator
Reverse Bend Calculator
Check return-flange clearance for reverse bends.
Open calculator
Box Depth Calculator
Check box depth and clearance for the final bends.
