Heat Treatment, Furnaces & Thermal Processing calculator
Thermal Processing Yield Calculator
Calculate thermal processing yield from accepted lots or parts, total processed quantity, and target yield. Use the rate and target gap to decide whether the process is on track or needs corrective action.
What this calculator does
- Calculate thermal processing yield from accepted lots or parts, total processed quantity, and target yield.
- Use it when heat treated output needs to be checked against first-pass quality goals.
- Measures first-pass yield for thermal processing output.
Formula used
- Thermal processing yield = accepted heat treated quantity ÷ total processed quantity × 100
- Gap to yield target = target thermal yield - thermal processing yield
Inputs explained
- Accepted heat treated quantity: Use the numerator from the inspection record, furnace log, shift report, or production summary.
- Total processed quantity: Use the matching total population for the same time period, furnace, recipe, and product family.
- Target thermal yield: Enter the internal KPI, customer requirement, or control plan target.
How to use the result
- Use it for quality reviews, shift reports, customer scorecards, and corrective action tracking.
- It does not separate defect modes. Pair it with scrap, rework, hardness, case depth, and distortion data.
Common questions
- What is the thermal processing yield calculator for? It calculates the percent of processed parts or lots accepted after heat treatment.
- What numbers should I enter? Use accepted quantity, total processed quantity, and the target yield for the same period and product family.
- How should I use the result? Use the gap to target to decide whether process correction, sorting, or containment is needed.
- When is this only an estimate? It is only an estimate when rework, concessions, or delayed lab results are not consistently counted.
