Fired Dimensional Yield at 99% target dimensional yield: a worked example

Push target dimensional yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a quality engineer needs to measure how many fired ceramic parts meet drawing dimensions after sintering or grinding

The inputs for this scenario

  • Parts within dimensional tolerance: 472 fired parts (unchanged)
  • Total parts measured: 520 fired parts (unchanged)
  • Target dimensional yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Fired dimensional yield = parts within tolerance ÷ total parts measured × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 90.77 % dimensional yield for fired dimensional yield, the number this scenario is built around.
  • At this operating point the engine returns 8.23 percentage points for dimensional yield gap.
  • At this operating point the engine returns 472 fired parts for parts within dimensional tolerance.
  • At this operating point the engine returns 520 fired parts for total parts measured.

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. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Fired dimensional yield: 90.77 % dimensional yield (headline result)
