Sheet Metal Stamping & Press Lines worked example

Coil Yield at 68% target coil yield benchmark: a worked example in sheet metal stamping & press lines

This worked example runs the coil yield numbers for a tougher week than the baseline: 68% target coil yield benchmark instead of the typical 95%. Coil yield tells you how much of every incoming coil of steel or aluminum actually leaves the stamping line as parts versus how much ends up as offal, skeleton and slugs.

The inputs for this scenario

Scrap or offal weight from coil: 8 units (held at the documented default)
Total coil weight consumed: 250 units (held at the documented default)
Target coil yield benchmark: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

The calculation starts from the formula this tool documents: Coil Yield rate = affected amount ÷ total amount.
Rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
Gap to target works out to 64.8 points at these inputs.
Affected count works out to 8 count at these inputs.
Total count works out to 250 count at these inputs.

How this compares with the baseline

Against the tool's baseline example, where target coil yield benchmark sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
Use it when evaluating a strip layout, auditing a supplier coil, or building the material-cost line of a stamping quote. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
