Fastener Manufacturing & Thread Rolling worked example
Wire Coil Yield at 99% target wire coil yield: a worked example
This scenario runs the wire coil yield calculation on the strong side: 99% target wire coil yield, with every other input held at its documented default. Use it when reviewing wire yield after drawing, cut-off, heading setup, coil butt loss, or fastener production scrap.
The inputs for this scenario
- Usable wire converted to accepted output: 4,850 lb or pieces (unchanged)
- Total wire issued from coil: 5,000 lb or pieces (unchanged)
- Target wire coil yield: 99 % (raised for this scenario; the documented default is 98)
Working through the calculation
- Applying the documented formula (Wire coil yield = usable output from coil รท total wire issued) to the inputs above produces each figure below.
- At this operating point the engine returns 97 % for wire coil yield, the number this scenario is built around.
- At this operating point the engine returns 2 points for gap to coil-yield target.
- At this operating point the engine returns 4,850 lb or pieces for usable output.
- At this operating point the engine returns 5,000 lb or pieces for wire issued.
How this compares with the baseline
- Against the tool's baseline example, where target wire coil yield sits at 98% and the headline result is 97 %, this scenario lands almost exactly on the baseline at 97 %.
- Use it per coil or per lot to monitor material utilization, validate cost-standard scrap allowances, and prioritize yield-loss investigations. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
Results at a glance
- Wire coil yield: 97 % (headline result)
