Profile Cut Length Yield at 70% target cut length yield: a worked example

Suppose target cut length yield falls to 70%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Measure yield from acceptable cut lengths versus total profile length extruded, including saw scrap and short pieces.

The inputs for this scenario

  • Accepted profile length after cutoff: 9,400 ft (held at the documented default)
  • Total profile length extruded: 10,000 ft (held at the documented default)
  • Target cut length yield: 70 % (the input this scenario stresses; the baseline uses 97)

Working through the calculation

  • The calculation starts from the formula this tool documents: Profile Cut Length Yield = accepted cut length รท total profile length extruded.
  • Profile cut length yield works out to 94 % at these inputs, and this is the headline figure for the scenario.
  • Cut length yield gap works out to -24 points at these inputs.
  • Accepted cut length works out to 9,400 count at these inputs.
  • Total extruded length works out to 10,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target cut length yield sits at 97% and the headline result is 94 %, this scenario lands almost exactly on the baseline at 94 %.
  • It computes the percentage of total extruded profile length accepted as saleable cut lengths, plus the point gap to your 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

  • Profile cut length yield: 94 % (headline result)
  • Cut length yield gap: -24 points
  • Accepted cut length: 9,400 count
  • Total extruded length: 10,000 count

Run it with your numbers

  • To rerun this with your own numbers, open the live Profile Cut Length Yield calculator, set target cut length yield to your actual value, and adjust the remaining inputs to match your operation.
