Fixture, Gauge & Workholding Management calculator
Fixture Capacity Calculator
Estimate good production output from fixtures, nests, pallets, or tombstones using parts per cycle, available cycles, fixture uptime, and first-pass yield. Use it when checking whether fixture count and workholding layout can support daily or shift demand.
What this calculator does
- Estimate good production output from fixtures, nests, pallets, or tombstones using parts per cycle, available cycles, fixture uptime, and first-pass yield.
- Use it when checking whether fixture count and workholding layout can support daily or shift demand.
- Estimates realistic good-part capacity from fixtures, pallets, tombstones, nests, or modular workholding.
Formula used
- Gross fixture capacity = accepted parts per fixture cycle × available fixture cycles
- Good fixture capacity = gross capacity × fixture or pallet availability × first-pass yield through fixture
Inputs explained
- Accepted parts per fixture cycle: Use the accepted part count per fixture load, nest, pallet, tombstone face, or workholding cycle.
- Available fixture cycles: Enter available cycles for the same shift, day, or schedule window.
- Fixture or pallet availability: Use fixture availability after cleaning, repair, queueing, setup, and machine-ready losses.
- First-pass yield through fixture: Use first-pass yield for parts produced from the fixture before rework or scrap.
How to use the result
- Use it for production scheduling, fixture count justification, pallet loading plans, and bottleneck reviews.
- It does not prove clamping stability, datum repeatability, tolerance capability, or inspection method validity. Validate critical fixtures with production trials and metrology data.
Common questions
- What information do I need before using the Fixture Capacity? Use parts per fixture cycle, available cycles, fixture availability, and first-pass yield for the same cell and time window.
- What does the result mean? It estimates good accepted production capacity after fixture availability and first-pass-yield losses.
- 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 good capacity to decide if more fixtures, additional pallets, extra nests, or setup changes are needed to meet demand.
