Metals, Steel, Aluminum & Coil Processing worked example
Coil Yield at 99% target coil yield: a worked example in metals, steel, aluminum & coil processing
What does the result look like when target coil yield reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when a slitting, cut-to-length, or blanking run needs a clean prime yield percentage and gap-to-target for the production board.
The inputs for this scenario
- Prime output weight: 24,000 lb (unchanged)
- Master coil weight processed: 25,000 lb (unchanged)
- Target coil yield: 99 % (raised for this scenario; the documented default is 95)
Working through the calculation
- Applying the documented formula (Coil yield = prime output weight ÷ master coil weight processed × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 96 % for coil yield, the number this scenario is built around.
- At this operating point the engine returns 3 points for yield gap to target.
- At this operating point the engine returns 24,000 count for prime output weight.
- At this operating point the engine returns 25,000 count for master coil weight processed.
How this compares with the baseline
- Against the tool's baseline example, where target coil yield sits at 95% and the headline result is 96 %, this scenario lands almost exactly on the baseline at 96 %.
- A figure at this level is achievable when target coil yield is genuinely sustained, not just peaked for a shift. Yield by weight does not tell you where loss occurred; a low number could be edge trim, crop ends, or in-process rejects, so pair it with a scrap breakdown to act on it.
