Composite Nesting Yield at 63% target nesting yield: a worked example

Suppose target nesting yield falls to 63%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate nesting yield for fabric, prepreg, core, or ply cutting operations.

The inputs for this scenario

  • Usable nested ply or core area: 840 sq ft (held at the documented default)
  • Issued material area for nesting: 980 sq ft (held at the documented default)
  • Target nesting yield: 63 % (the input this scenario stresses; the baseline uses 88)

Working through the calculation

  • The calculation starts from the formula this tool documents: Composite Nesting Yield = usable nested ply or core area ÷ issued material area for nesting × 100.
  • composite nesting yield works out to 85.71 % at these inputs, and this is the headline figure for the scenario.
  • composite nesting yield gap to target works out to -22.71 points at these inputs.
  • usable nested ply or core area works out to 840 count at these inputs.
  • issued material area for nesting works out to 980 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target nesting yield sits at 88% and the headline result is 85.71 %, this scenario lands almost exactly on the baseline at 85.71 %.
  • It computes the ratio of usable nested area to issued material area as a percentage, and reports how many points you are above or below your yield 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.

Results at a glance

  • composite nesting yield: 85.71 % (headline result)
  • composite nesting yield gap to target: -22.71 points
  • usable nested ply or core area: 840 count
  • issued material area for nesting: 980 count

Run it with your numbers
