Inspection Capacity at 65% expected uptime: a worked example in quality & metrology

Here is what the math looks like when conditions slip. We hold every other input steady and drop expected uptime to 65%, then walk the calculation through step by step. Estimate realistic inspection capacity from parts inspected per cycle, available cycles, expected uptime, and first-pass yield.

The inputs for this scenario

  • Parts inspected per cycle: 4 parts / cycle (held at the documented default)
  • Available cycles: 480 cycles (held at the documented default)
  • Expected uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross inspection capacity = parts inspected per cycle × available cycles.
  • Good inspection capacity works out to 1,211 parts at these inputs, and this is the headline figure for the scenario.
  • Gross inspection capacity works out to 1,920 parts at these inputs.
  • Downtime loss works out to 672 parts at these inputs.
  • First-pass yield loss works out to 37.44 parts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected uptime sits at 90% and the headline result is 1,676 parts, this scenario comes in 27.78% below the baseline at 1,211 parts.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to expected uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses steady-state uptime and yield averages, so it will not capture bursty downtime, gauge R&R delays, or a specific hard-to-inspect part mix.

Results at a glance

  • Good inspection capacity: 1,211 parts (headline result)
  • Gross inspection capacity: 1,920 parts
  • Downtime loss: 672 parts
  • First-pass yield loss: 37.44 parts
