UV Shadowing Risk Score with part geometry shadow severity of 28 score: a worked example

Suppose part geometry shadow severity falls to 28 score. This page works the full calculation at that level so you can see exactly which result moves and by how much. Score the cure risk on parts with 3D geometry, undercuts, or fixturing that blocks line-of-sight from the UV lamp.

The inputs for this scenario

  • Part geometry shadow severity: 28 score (the input this scenario stresses; the baseline uses 55)
  • Fixture / conveyor lane occlusion risk: 30 score (held at the documented default)
  • Beam angle & line-speed detection risk: 20 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Risk score = (geometry × 0.5) + (fixture × 0.3) + (exposure × 0.2).
  • UV shadowing risk score works out to 26.7 shadow risk score at these inputs, and this is the headline figure for the scenario.
  • Geometry exposure (severity) works out to 28 score at these inputs.
  • Fixture / lane (occurrence) works out to 30 score at these inputs.
  • Exposure angle / speed works out to 20 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where part geometry shadow severity sits at 55 score and the headline result is 37.5 shadow risk score, this scenario comes in 28.8% below the baseline at 26.7 shadow risk score.
  • It computes a single shadowing risk score by weighting geometry severity at 0.5, fixture/lane occlusion at 0.3 and beam-angle/speed detectability at 0.2. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • UV shadowing risk score: 26.7 shadow risk score (headline result)
  • Geometry exposure (severity): 28 score
  • Fixture / lane (occurrence): 30 score
  • Exposure angle / speed: 20 score
