Electrode Width Utilization at 99% target width utilization: a worked example

Push target width utilization up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a coating or slitting engineer needs to evaluate electrode layout, edge trim, and usable web width

The inputs for this scenario

  • Usable coated electrode width: 920 mm (unchanged)
  • Available foil/web width: 1,000 mm (unchanged)
  • Target width utilization: 99 % (raised for this scenario; the documented default is 94)

Working through the calculation

  • Applying the documented formula (Electrode width utilization = usable coated electrode width รท available foil/web width) to the inputs above produces each figure below.
  • At this operating point the engine returns 92 % width utilization for electrode width utilization, the number this scenario is built around.
  • At this operating point the engine returns 7 points for width utilization gap.
  • At this operating point the engine returns 920 mm for usable coated width.
  • At this operating point the engine returns 1,000 mm for available foil/web width.

How this compares with the baseline

  • Against the tool's baseline example, where target width utilization sits at 94% and the headline result is 92 % width utilization, this scenario lands almost exactly on the baseline at 92 % width utilization.
  • It computes the ratio of usable coated electrode width to total foil web width, and the gap between that utilization and your target. 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

  • Electrode width utilization: 92 % width utilization (headline result)
  • Width utilization gap: 7 points
  • Usable coated width: 920 mm
  • Available foil/web width: 1,000 mm
