Tube, Pipe & Profile Forming worked example

Tube Cut Length Yield at 99% target first-pass yield: a worked example

What does the result look like when target first-pass yield reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when tube cut length yield in tube, pipe and profile forming needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Off-length / scrap cuts: 8 units (unchanged)
  • Total cuts produced: 250 units (unchanged)
  • Target first-pass yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Tube Cut Length Yield rate = affected amount รท total amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 ft for rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for gap to target.
  • At this operating point the engine returns 8 count for affected count.
  • At this operating point the engine returns 250 count for total count.

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 ft, this scenario lands almost exactly on the baseline at 3.2 ft.
  • A figure at this level is achievable when target first-pass yield is genuinely sustained, not just peaked for a shift. It only counts pieces you flagged as off-length; it will not catch cosmetic, wall-thickness, or ovality defects, so a 'good' cut-length yield does not mean a good part.

Results at a glance

  • Rate: 3.2 ft (headline result)
  • Gap to target: 95.8 points
  • Affected count: 8 count
  • Total count: 250 count
