Acoustic Trim Yield at 99% target trim yield: a worked example

Push target trim yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a manufacturing engineer needs to measure trim yield for acoustic components or NVH kits

The inputs for this scenario

  • Usable trimmed acoustic parts: 940 parts (unchanged)
  • Total parts cut and trimmed: 1,000 parts (unchanged)
  • Target trim yield: 99 % (raised for this scenario; the documented default is 96)

Working through the calculation

  • Applying the documented formula (Trim yield = usable trimmed parts รท total parts cut) to the inputs above produces each figure below.
  • At this operating point the engine returns 94 % for trim yield, the number this scenario is built around.
  • At this operating point the engine returns 5 points for gap to target.
  • At this operating point the engine returns 940 parts for usable trimmed parts.
  • At this operating point the engine returns 1,000 parts for total parts cut.

How this compares with the baseline

  • Against the tool's baseline example, where target trim yield sits at 96% and the headline result is 94 %, this scenario lands almost exactly on the baseline at 94 %.
  • It computes trim yield as usable trimmed parts divided by total parts cut, then shows the gap in points to your target yield. 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

  • Trim yield: 94 % (headline result)
  • Gap to target: 5 points
  • Usable trimmed parts: 940 parts
  • Total parts cut: 1,000 parts
