Rare Earth Magnet & Motor Materials worked example

Dimensional Yield at 68% target dimensional yield rate: a worked example in rare earth magnet & motor materials

Suppose target dimensional yield rate falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate dimensional yield for rare earth magnet and motor materials using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Magnets within dimensional tolerance: 8 count (held at the documented default)
  • Magnets gauged in the lot: 250 count (held at the documented default)
  • Target dimensional yield rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Dimensional yield rate = dimensional yield count ÷ total dimensional yield population × 100.
  • Dimensional yield rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Dimensional yield gap to target works out to 64.8 points at these inputs.
  • Dimensional yield count works out to 8 count at these inputs.
  • Total dimensional yield population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target dimensional yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the dimensional yield rate as in-tolerance count over total gauged, then reports the gap in points to your target yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
