Pultrusion & Continuous Composite Profiles worked example

Cut Length Yield at 68% target cut-length yield: a worked example in pultrusion & continuous composite profiles

Here is what the math looks like when conditions slip. We hold every other input steady and drop target cut-length yield to 68%, then walk the calculation through step by step. Cut Length Yield is the share of pultruded profiles that come off the flying cut-off saw at the correct length and pass gate inspection, versus everything the line cut in the run.

The inputs for this scenario

  • In-spec cut lengths passing gate inspection: 8 units (held at the documented default)
  • Total profiles cut in the run: 250 units (held at the documented default)
  • Target cut-length yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cut Length Yield rate = affected amount รท total amount.
  • Rate works out to 3.2 ft at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to 64.8 points at these inputs.
  • Affected count works out to 8 count at these inputs.
  • Total count works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target cut-length yield sits at 95% and the headline result is 3.2 ft, this scenario lands almost exactly on the baseline at 3.2 ft.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target cut-length yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It only counts length conformance at the saw; it says nothing about surface defects, void content, or off-length pieces that get recut and recovered.
