Precision Gearbox Yield at 99% target first-pass yield: a worked example

This scenario runs the precision gearbox yield calculation on the strong side: 99% target first-pass yield, with every other input held at its documented default. Use it when precision gearbox yield in surgical robotics manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Gearboxes passing precision inspection: 8 count (unchanged)
  • Gearboxes inspected: 250 count (unchanged)
  • Target first-pass yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Precision gearbox yield rate = precision gearbox yield count ÷ total precision gearbox yield population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for precision gearbox yield rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for precision gearbox yield gap to target.
  • At this operating point the engine returns 8 count for precision gearbox yield count.
  • At this operating point the engine returns 250 count for total precision gearbox yield population.

How this compares with the baseline

  • Against the tool's baseline example, where target first-pass yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it during incoming inspection, supplier scorecarding, or process-capability reviews of a precision-gear line. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
