Powder Metallurgy & Sintered Parts worked example

Part Yield at 68% target yield benchmark: a worked example

This worked example runs the part yield numbers for a tougher week than the baseline: 68% target yield benchmark instead of the typical 95%. Part Yield in powder metallurgy tracks the share of pressed-and-sintered components that fail inspection — cracks, laminations, density gradients, dimensional drift after sizing, or blister defects from poor dewaxing.

The inputs for this scenario

Rejected or scrapped parts: 8 units (held at the documented default)
Total parts pressed & sintered: 250 units (held at the documented default)
Target yield benchmark: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

The calculation starts from the formula this tool documents: Part Yield rate = affected amount ÷ total amount.
Rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
Gap to target works out to 64.8 points at these inputs.
Affected count works out to 8 count at these inputs.
Total count works out to 250 count at these inputs.

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 %.
Use it during shift reviews, PPAP capability studies, or when a defect trend appears and you need to size the loss against a goal. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
