Precision Springs, Stampings & Micro-Formed Components worked example

Dimensional Yield at 68% target dimensional yield rate: a worked example in precision springs, stampings & micro-formed components

Here is what the math looks like when conditions slip. We hold every other input steady and drop target dimensional yield rate to 68%, then walk the calculation through step by step. Estimate dimensional yield for precision springs, stampings and micro-formed components using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Parts within dimensional tolerance: 8 count (held at the documented default)
  • Total parts measured: 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 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target dimensional yield rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It reflects only the sample measured — a small or biased sample can badly misstate true yield, and a single out-of-tolerance dimension fails the part even if all others pass.
