Heat Treatment, Furnaces & Thermal Processing worked example

Thermal Processing Yield at 71% target yield: a worked example

This worked example runs the thermal processing yield numbers for a tougher week than the baseline: 71% target yield instead of the typical 98%. Calculate thermal processing yield for Heat Treatment, Furnaces & Thermal Processing: accepted heat-treated parts as a share of total parts processed.

The inputs for this scenario

  • Accepted parts: 960 units (held at the documented default)
  • Total parts processed: 1,000 units (held at the documented default)
  • Target yield: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Thermal processing yield = accepted parts ÷ total parts processed × 100.
  • Thermal processing yield works out to 96 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -25 points at these inputs.
  • Accepted parts works out to 960 count at these inputs.
  • Total parts processed works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target yield sits at 98% and the headline result is 96 %, this scenario lands almost exactly on the baseline at 96 %.
  • Use it at the end of a furnace run, shift, or lot to track quality and flag recipes drifting away from target. 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.

Results at a glance

  • Thermal processing yield: 96 % (headline result)
  • Gap to target: -25 points
  • Accepted parts: 960 count
  • Total parts processed: 1,000 count
