Sheet Metal Stamping & Press Lines worked example

Feed Pitch at 99% line efficiency: a worked example

Push line efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when feed pitch in sheet metal stamping and press lines is being committed and you need a throughput number you can defend.

The inputs for this scenario

  • Good parts stamped this run: 1,200 units (unchanged)
  • Press line uptime: 8 hr (unchanged)
  • Line efficiency (OEE-adjusted): 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Raw feed pitch = completed output รท runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 149 units for effective throughput, the number this scenario is built around.
  • At this operating point the engine returns 150 units for raw throughput.
  • At this operating point the engine returns 99 % for efficiency.
  • At this operating point the engine returns 8 hr for runtime.

How this compares with the baseline

  • Against the tool's baseline example, where line efficiency sits at 90% and the headline result is 135 units, this scenario comes in 10% above the baseline at 149 units.
  • It computes effective parts-per-hour throughput for a stamping press line by dividing good output by uptime, then scaling by line efficiency. 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

  • Effective throughput: 149 units (headline result)
  • Raw throughput: 150 units
  • Efficiency: 99 %
  • Runtime: 8 hr
