Powder Metallurgy & Sintered Parts worked example

Part Yield at 99% target yield benchmark: a worked example

What does the result look like when target yield benchmark reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when part yield in powder metallurgy and sintered parts needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Rejected or scrapped parts: 8 units (unchanged)
  • Total parts pressed & sintered: 250 units (unchanged)
  • Target yield benchmark: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Part Yield rate = affected amount รท total amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for gap to target.
  • At this operating point the engine returns 8 count for affected count.
  • At this operating point the engine returns 250 count for total count.

How this compares with the baseline

  • Against the tool's baseline example, where target yield benchmark sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target yield benchmark is genuinely sustained, not just peaked for a shift. It treats every rejected part the same, so it will not distinguish a cheap green reject caught before sintering from an expensive part scrapped after machining and heat treat.

Results at a glance

  • Rate: 3.2 % (headline result)
  • Gap to target: 95.8 points
  • Affected count: 8 count
  • Total count: 250 count
