Sheet Metal Stamping & Press Lines worked example

Part Cost Per Stroke at 92% good-part yield factor: a worked example

Push good-part yield factor up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when part cost per stroke in sheet metal stamping and press lines is being put through a sheet metal stamping and press lines weighted-cost review.

The inputs for this scenario

  • Parts produced across the run: 100 units (unchanged)
  • Fully-burdened cost per part: 45 $ / unit (unchanged)
  • Good-part yield factor: 92 % (raised for this scenario; the documented default is 80)
  • Die setup and amortization cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Part Cost Per Stroke cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where good-part yield factor sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes the yield-weighted total cost of a stamping run plus fixed setup, and divides by quantity to give cost per part. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Weighted cost: 4,390 $ (headline result)
  • Per piece value: 43.9 $ / piece
  • Captured value: 4,140 $
  • Fixed adjustment: 250 $
