Heat Treat Distortion Scrap Cost with scrapped heat-treated components of 110 parts: a worked example

This scenario runs the heat treat distortion scrap cost calculation on the strong side: scrapped heat-treated components of 110 parts, with every other input held at its documented default. a gear or bearing operation needs to estimate the financial impact of heat-treat distortion scrap on a production lot

The inputs for this scenario

  • Scrapped heat-treated components: 110 parts (raised for this scenario; the documented default is 42)
  • Cost per scrapped component: 185 $ / part (unchanged)
  • Fixed heat-treat batch cost: 2,400 $ (unchanged)
  • Containment and rework overhead: 950 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Scrapped component value = scrapped components × cost per scrapped component) to the inputs above produces each figure below.
  • At this operating point the engine returns 23,700 $ for total heat-treat distortion scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 215 $ / rejected part for scrap cost per rejected component.
  • At this operating point the engine returns 20,350 $ for scrapped component value.
  • At this operating point the engine returns 3,350 $ for batch and containment adders.

How this compares with the baseline

  • Against the tool's baseline example, where scrapped heat-treated components sits at 42 parts and the headline result is 11,120 $, this scenario comes in 113% above the baseline at 23,700 $.
  • Use it after a distortion-driven rejection to size the true loss, build a cost-of-poor-quality case, or justify quench, fixture, or process changes. 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 heat-treat distortion scrap cost: 23,700 $ (headline result)
  • Scrap cost per rejected component: 215 $ / rejected part
  • Scrapped component value: 20,350 $
  • Batch and containment adders: 3,350 $
