Fired Dimensional Yield at 68% target dimensional yield: a worked example

Suppose target dimensional yield falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate dimensional yield for fired ceramic parts from parts within tolerance, total parts measured, and the dimensional yield target.

The inputs for this scenario

  • Parts within dimensional tolerance: 472 fired parts (held at the documented default)
  • Total parts measured: 520 fired parts (held at the documented default)
  • Target dimensional yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fired dimensional yield = parts within tolerance ÷ total parts measured × 100.
  • Fired dimensional yield works out to 90.77 % dimensional yield at these inputs, and this is the headline figure for the scenario.
  • Dimensional yield gap works out to -22.77 percentage points at these inputs.
  • Parts within dimensional tolerance works out to 472 fired parts at these inputs.
  • Total parts measured works out to 520 fired parts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target dimensional yield sits at 95% and the headline result is 90.77 % dimensional yield, this scenario lands almost exactly on the baseline at 90.77 % dimensional yield.
  • It computes the percentage of measured fired parts that fall within dimensional tolerance and the percentage-point gap between that yield and your target. 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.
