Press Brake Setup and First Piece Inspection Checklist

A disciplined setup and first piece check prevents the most expensive press brake failure: running a full batch at the wrong angle. This checklist follows the order an operator works in, from paperwork to release.

How to use it

Print the checklist or complete it on a tablet at the machine. Work through each group in order, mark items as you confirm them, and do not release the run until every critical item is done. Export the completed list as a PDF and attach it to the traveler or the job record so a quality auditor can see what was verified and by whom.

Use it at every setup, not only for new parts.
Repeat the first piece checks after any tool or lot change.
Log actual setup time to improve future estimates.

Why first piece matters

Springback varies with the material lot, thickness within tolerance and grain direction. A program that worked last month can give a different angle on a new coil. Measuring every bend on the first piece, adjusting, and saving the correction to the program stops that drift from becoming a batch of scrap. For regulated work, the first piece record is also evidence of process control.

Safety and tooling checks

Guarding, tool clamping and tonnage limits are not optional items. Tooling has a rated maximum load per unit length, and exceeding it can damage the tool or the machine. Confirm tool seating and clamping before approaching the part, and never bypass guarding to speed up a setup. Follow your site lockout and safety rules in addition to this list.

Common mistakes

Operators often skip angle measurement on secondary bends once the first one looks right, run first pieces on scrap of a different thickness, or forget to update the program with the correction. Also common is leaving the traveler on an old revision, which results in bending to the previous design.

Frequently Asked Questions

How many first pieces should be checked?

At minimum one, measured on all bends. Many shops require a second piece to confirm the correction before running. Follow your quality procedure and customer requirements.

How often should parts be checked during a run?

It depends on the part risk and customer requirement. Common approaches are a check at a fixed interval, such as every 25 or 50 parts, plus a check after any interruption, tool change or new material lot.

What tool measures bend angle?

Digital protractors, angle gauges, templates or a coordinate measuring system. Use a calibrated tool with resolution suitable for the angle tolerance, and measure at the same location each time.

Why record setup time?

Setup is a major cost on small lots. Recording actual setup against the estimate improves future quotes and shows where tooling or program preparation can be improved.
