UV Curing worked example

UV Oxygen Inhibition Risk Score with cure-zone atmosphere o₂ level risk of 30 score: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop cure-zone atmosphere o₂ level risk to 30 score, then walk the calculation through step by step. Score the risk of oxygen-inhibition surface-cure problems on a UV chemistry from atmosphere O₂ level, chemistry type, and cure intensity.

The inputs for this scenario

  • Cure-zone atmosphere O₂ level risk: 30 score (the input this scenario stresses; the baseline uses 60)
  • Resin chemistry O₂ sensitivity risk: 50 score (held at the documented default)
  • UV dose and dwell adequacy risk: 40 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Risk score = (atmosphere × 0.4) + (chemistry × 0.4) + (intensity × 0.2).
  • O₂ inhibition risk score works out to 39.5 O₂ inhibition risk score at these inputs, and this is the headline figure for the scenario.
  • Atmosphere O₂ works out to 30 score at these inputs.
  • Chemistry sensitivity works out to 50 score at these inputs.
  • Intensity / dwell works out to 40 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cure-zone atmosphere o₂ level risk sits at 60 score and the headline result is 51.5 O₂ inhibition risk score, this scenario comes in 23.3% below the baseline at 39.5 O₂ inhibition risk score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to cure-zone atmosphere o₂ level risk, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The inputs are engineering-judgment scores, not lab measurements, so the output only ranks relative risk — it never replaces an actual cure test on the real film.
