Progressive Die Scrap at 68% target progressive die scrap rate: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target progressive die scrap rate to 68%, then walk the calculation through step by step. Estimate progressive die scrap for precision springs, stampings and micro-formed components using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Progressive die scrap count: 8 count (held at the documented default)
  • Total progressive die scrap population: 250 count (held at the documented default)
  • Target progressive die scrap rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Progressive die scrap rate = progressive die scrap count ÷ total progressive die scrap population × 100.
  • Progressive die scrap rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Progressive die scrap gap to target works out to 64.8 points at these inputs.
  • Progressive die scrap count works out to 8 count at these inputs.
  • Total progressive die scrap population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target progressive die scrap rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target progressive die scrap rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. A single scrap rate hides where in the die parts fail; two identical rates can mean a stray misfeed or a systematically worn station, so pair it with defect-location data.

Results at a glance

  • Progressive die scrap rate: 3.2 % (headline result)
  • Progressive die scrap gap to target: 64.8 points
  • Progressive die scrap count: 8 count
  • Total progressive die scrap population: 250 count
