Strip Layout Yield at 68% target strip layout yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target strip layout yield to 68%, then walk the calculation through step by step. Strip layout yield measures how efficiently a progressive-die strip converts incoming stock into parts versus web, carrier and skeleton scrap.

The inputs for this scenario

  • Strip material lost to web and skeleton: 8 units (held at the documented default)
  • Total strip material fed: 250 units (held at the documented default)
  • Target strip layout yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Strip Layout 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 strip layout yield 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 strip layout yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It captures the strip's scrap ratio by weight but not stamping speed or die complexity — a higher-yield layout may need more stations or slower feed, so weigh it against throughput.

Results at a glance

  • Rate: 3.2 % (headline result)
  • Gap to target: 64.8 points
  • Affected count: 8 count
  • Total count: 250 count
