Fixture, Gauge & Workholding Management calculator

Fixture Design Workload Calculator

Estimate engineering hours required to design, review, detail, release, and support fixtures, gauges, jigs, nests, or workholding. Use it when planning tooling engineer capacity, fixture design queues, launch support, or outsourced design packages.

What this calculator does

  • Estimate engineering hours required to design, review, detail, release, and support fixtures, gauges, jigs, nests, or workholding.
  • Use it when planning tooling engineer capacity, fixture design queues, launch support, or outsourced design packages.
  • Estimates tooling engineering workload for fixture, gauge, jig, nest, pallet, and workholding design work.

Formula used

  • Base fixture design workload time = fixture designs or revisions ÷ completed designs per engineering hour
  • Required fixture design workload time = base fixture design workload time × allowance factor

Inputs explained

  • Fixture designs or revisions: Enter new fixture designs, gauge designs, jig designs, nest revisions, or workholding updates in the engineering queue.
  • Completed designs per engineering hour: Use a realistic completion rate from similar CAD, detailing, tolerance, datum, clamp, and drawing-release work.
  • Review, ECO, and tryout allowance: Add allowance for design reviews, ECOs, supplier questions, tryout support, and metrology feedback.

How to use the result

  • Use it to schedule fixture designers, decide what to outsource, and protect launch timing when many tools are needed at once.
  • It assumes standard work, trained operators or engineers, available tooling, released drawings, current setup sheets, and no unusual fixture damage or dimensional investigation.

Common questions

  • What information do I need before using the Fixture Design Workload? Use design or revision count, design completion rate, and allowance for reviews, changes, supplier support, and tryout feedback.
  • What does the result mean? It estimates required labor hours after setup, verification, handling, and delay allowance are applied.
  • When is the result only an estimate? It is an estimate when part mix, datum scheme, tolerance stack, clamp layout, operator method, inspection plan, gauge condition, calibration status, maintenance history, machine uptime, or production volume differs from the assumptions entered.
  • What decision can I make from the result? Use the hours to assign engineers, outsource design packages, sequence tool releases, or negotiate launch dates around fixture design capacity.
