UV Curing worked example

UV Cure Process Window with current line speed of 16 ft / min: a worked example

This worked example runs the uv cure process window numbers for a tougher week than the baseline: current line speed of 16 ft / min instead of the typical 32 ft / min. Check whether the current line speed (or any other process variable) sits inside the validated UV cure window - and how close it is to either limit.

The inputs for this scenario

  • Current line speed (operating point): 16 ft / min (the input this scenario stresses; the baseline uses 32)
  • Slowest allowed speed (overcure floor): 22 ft / min (held at the documented default)
  • Fastest allowed speed (undercure ceiling): 48 ft / min (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Inside window = (window min ≤ operating point ≤ window max).
  • In / out of window works out to 0 outside at these inputs, and this is the headline figure for the scenario.
  • Margin to nearest limit works out to -6 ft / min at these inputs.
  • Window minimum (overcure floor) works out to 22 ft / min at these inputs.
  • Window maximum (undercure ceiling) works out to 48 ft / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where current line speed sits at 32 ft / min and the headline result is 1 inside, this scenario comes in 100% below the baseline at 0 outside.
  • Use it at job setup, after a lamp change, or whenever an operator questions whether the current belt speed is still qualified for the coating being run. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • In / out of window: 0 outside (headline result)
