UV Curing worked example

UV Cure Rework / Scrap Cost with defective parts of 600 parts: a worked example

This scenario runs the uv cure rework / scrap cost calculation on the strong side: defective parts of 600 parts, with every other input held at its documented default. Use it after a defect event to size the loss, build the business case for tightening the cure spec, or quantify the savings of preventing the next escape.

The inputs for this scenario

  • Defective parts: 600 parts (raised for this scenario; the documented default is 240)
  • Rework or scrap cost per part: 8 $ / part (unchanged)
  • Disposition / containment labor: 650 $ (unchanged)
  • Overhead / customer impact: 300 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable cost = defective parts × cost per part) to the inputs above produces each figure below.
  • At this operating point the engine returns 5,750 $ per defect event for total cure defect event cost, the number this scenario is built around.
  • At this operating point the engine returns 9.58 $ / defective part for cost per defective part.
  • At this operating point the engine returns 4,800 $ for rework / scrap material.
  • At this operating point the engine returns 950 $ for disposition + overhead.

How this compares with the baseline

  • Against the tool's baseline example, where defective parts sits at 240 parts and the headline result is 2,870 $ per defect event, this scenario comes in 100% above the baseline at 5,750 $ per defect event.
  • Use it right after a cure-related reject batch, customer return, or containment action to put a defensible dollar figure on the event for corrective-action and capital-justification cases. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total cure defect event cost: 5,750 $ per defect event (headline result)
  • Cost per defective part: 9.58 $ / defective part
  • Rework / scrap material: 4,800 $
  • Disposition + overhead: 950 $
