Gear Tooth Inspection Workload at 29% setup and recheck allowance: a worked example

This scenario runs the gear tooth inspection workload calculation on the strong side: 29% setup and recheck allowance, with every other input held at its documented default. a gear manufacturer needs to schedule CMM, gear checker, or manual tooth inspection workload for a production lot

The inputs for this scenario

  • Tooth features or gears to inspect: 360 features or gears (unchanged)
  • Tooth inspection rate: 45 features / hr (unchanged)
  • Setup and recheck allowance: 29 % (raised for this scenario; the documented default is 25)

Working through the calculation

  • Applying the documented formula (Base tooth inspection time = tooth features or gears to inspect รท tooth inspection rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 10.32 hr for required tooth inspection workload, the number this scenario is built around.
  • At this operating point the engine returns 8 hr for base tooth inspection time.
  • At this operating point the engine returns 29 % for setup and recheck allowance.
  • At this operating point the engine returns 45 features / hr for tooth inspection rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup and recheck allowance sits at 25% and the headline result is 10 hr, this scenario comes in 3.2% above the baseline at 10.32 hr.
  • Use it when staffing a metrology cell, scheduling analytical gear-checker time, or quoting inspection-intensive gear work. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required tooth inspection workload: 10.32 hr (headline result)
