Press Brake Tonnage Calculator

FirstBend is setup memory for press brake shops. When a part comes back, open it and see exactly how it was set up and verified last time, instead of searching notebooks or asking around.

FirstBend is a setup record, not a calculator. It does not compute tonnage, bend allowance or K-factor. It keeps the values your operators actually used and proved on the machine.

SAVE EVERY SETUP BY PART AND REVISION
• Organize jobs by part number and revision
• Record the machine, program number, material and thickness
• Record punch and die tooling, including the V-opening
• Add the target angle, flange and backgauge for each bend
• Attach tooling photos so the next operator sees punch and die orientation

RUN AND VERIFY THE FIRST PIECE
• Step through each bend on the first-piece check
• Enter the measured angle and flange and see the deviation from target
• Log an attempt and re-test, or mark the bend as passed
• Add notes such as springback observations

KEEP A GOLDEN SETUP
• Save an operator-confirmed setup as a Golden Setup for future runs
• Copy a proven setup into a new draft for the next run
• Mark a setup as Deprecated when tooling, machine condition or material behavior changes, and keep the history
• See which setup belongs to the current production revision

SHARE AND BACK UP
• Generate and print clean PDF setup sheets for the shop floor (FirstBend Pro)
• Export a ZIP backup of parts, revisions, setups, attempts and tooling photos, and restore it later
• Records stay on this device unless you export or share them

PLANS
The free version stores up to 3 parts. FirstBend Pro is a one-time purchase that adds unlimited parts and PDF setup sheets. No monthly subscription.

WHO IT IS FOR
Press brake operators, setup technicians, shop leads and small sheet metal fabrication shops that run repeat jobs.

IMPORTANT
FirstBend records setup data entered by operators. It does not determine whether a setup is safe, compliant or suitable for a job. Operators are responsible for verifying tooling, machine limits, clearances and shop requirements before running a part.
