Fixture, Gauge & Workholding Management worked example

Fixture Utilization at 58% target fixture utilization rate: a worked example in fixture, gauge & workholding management

Here is what the math looks like when conditions slip. We hold every other input steady and drop target fixture utilization rate to 58%, then walk the calculation through step by step. Calculate how often available fixtures, nests, pallets, tombstones, or inspection fixtures are actually used compared with the available fixture population.

The inputs for this scenario

  • Fixtures used during the period: 138 fixtures (held at the documented default)
  • Fixtures available for the period: 180 fixtures (held at the documented default)
  • Target fixture utilization rate: 58 % (the input this scenario stresses; the baseline uses 80)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fixture Utilization rate = fixtures used during the period ÷ fixtures available for the period × 100.
  • Fixture Utilization rate works out to 76.67 % at these inputs, and this is the headline figure for the scenario.
  • Fixture Utilization gap to target works out to -18.67 points at these inputs.
  • Fixtures used during the period works out to 138 fixtures at these inputs.
  • Fixtures available for the period works out to 180 fixtures at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target fixture utilization rate sits at 80% and the headline result is 76.67 %, this scenario lands almost exactly on the baseline at 76.67 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target fixture utilization rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It is a snapshot ratio of counts, so it doesn't capture how long each fixture ran; a fixture used for one job all period counts the same as one used continuously.

Results at a glance

  • Fixture Utilization rate: 76.67 % (headline result)
  • Fixture Utilization gap to target: -18.67 points
  • Fixtures used during the period: 138 fixtures
  • Fixtures available for the period: 180 fixtures
