Metals, Steel, Aluminum & Coil Processing worked example
Nesting Yield at 99% target nesting yield: a worked example in metals, steel, aluminum & coil processing
This scenario runs the nesting yield calculation on the strong side: 99% target nesting yield, with every other input held at its documented default. Use it when a programmer or estimator wants nesting efficiency against target before releasing a laser, plasma, or punch nest.
The inputs for this scenario
- Net part area nested per sheet: 420 in² (unchanged)
- Usable sheet area: 480 in² (unchanged)
- Target nesting yield: 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Nesting yield = net part area per sheet ÷ sheet area × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 87.5 % for nesting yield, the number this scenario is built around.
- At this operating point the engine returns 11.5 points for yield gap to target.
- At this operating point the engine returns 420 count for net part area per sheet.
- At this operating point the engine returns 480 count for sheet area.
How this compares with the baseline
- Against the tool's baseline example, where target nesting yield sits at 90% and the headline result is 87.5 %, this scenario lands almost exactly on the baseline at 87.5 %.
- Use it when reviewing a nest layout, comparing two part orientations, or validating a quote's scrap allowance before releasing a job to the laser or turret. 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
