Sheet Metal Stamping & Press Lines worked example

Material Cost Per Part at 92% material yield: a worked example

Push material yield up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when material cost per part 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 in the lot: 100 units (unchanged)
  • Blank coil cost per part: 45 $ / unit (unchanged)
  • Material yield (nesting utilization): 92 % (raised for this scenario; the documented default is 80)
  • Fixed coil handling & scrap-credit cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Material Cost Per Part 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 material yield sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes total lot material cost as quantity times coil cost times yield factor plus a fixed cost, then divides by quantity for per-piece material cost. 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 $
