Electrode Width Utilization at 68% target width utilization: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target width utilization to 68%, then walk the calculation through step by step. Calculate electrode web width utilization from coated usable width, available foil width, and target utilization.

The inputs for this scenario

  • Usable coated electrode width: 920 mm (held at the documented default)
  • Available foil/web width: 1,000 mm (held at the documented default)
  • Target width utilization: 68 % (the input this scenario stresses; the baseline uses 94)

Working through the calculation

  • The calculation starts from the formula this tool documents: Electrode width utilization = usable coated electrode width ÷ available foil/web width.
  • Electrode width utilization works out to 92 % width utilization at these inputs, and this is the headline figure for the scenario.
  • Width utilization gap works out to -24 points at these inputs.
  • Usable coated width works out to 920 mm at these inputs.
  • Available foil/web width works out to 1,000 mm at these inputs.

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.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target width utilization, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It only addresses cross-web width utilization — it ignores length-direction losses from start-stop coating, defects and changeovers, so it overstates total material yield on its own.
