Foam Cut Yield at 99% yield target: a worked example
What does the result look like when yield target reaches 99%? The full calculation is worked below with real intermediate numbers. Use this when reviewing foam cutting room efficiency, comparing nesting layouts, or setting scrap reduction targets for polyurethane, memory foam, or latex cutting operations.
The inputs for this scenario
- Usable foam pieces produced: 230 pieces (unchanged)
- Total foam pieces attempted: 250 pieces (unchanged)
- Yield target: 99 % (raised for this scenario; the documented default is 95)
Working through the calculation
- Applying the documented formula (Foam cut yield (%) = usable pieces ÷ total pieces attempted × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 92 % for rate, the number this scenario is built around.
- At this operating point the engine returns 7 points for gap to target.
- At this operating point the engine returns 230 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 yield target sits at 95% and the headline result is 92 %, this scenario lands almost exactly on the baseline at 92 %.
- A figure at this level is achievable when yield target is genuinely sustained, not just peaked for a shift. Piece-count yield treats a small trim reject and a full-core scrap equally; it does not weight by foam volume or dollar value, so a few large scrapped cores can hurt cost more than the yield number suggests.
Results at a glance
- Rate: 92 % (headline result)
