Heat Treatment, Furnaces & Thermal Processing calculator
Part Distortion Risk Calculator
Score part distortion risk from severity, occurrence, and detection risk for heat treated parts. Score the risk consistently so quality, metallurgy, and production can rank action items before release.
What this calculator does
- Score part distortion risk from severity, occurrence, and detection risk for heat treated parts.
- Use it when geometry, fixturing, quench severity, residual stress, or section changes could create unacceptable distortion.
- Creates a weighted risk score for heat treat distortion before or after a run.
Formula used
- Part Distortion Risk score = distortion impact severity × 0.40 + distortion occurrence likelihood × 0.35 + distortion detection risk × 0.25
Inputs explained
- Distortion impact severity: Higher means the consequence is more serious for quality, fit, performance, scrap, or customer use.
- Distortion occurrence likelihood: Higher means the condition is more likely for this material, geometry, fixture, or recipe.
- Distortion detection risk: Higher means the current controls are less likely to catch the issue before release.
How to use the result
- Use it during FMEA, launch review, fixture review, quench review, or corrective action prioritization.
- It does not predict actual dimensional movement. Use trials, metrology, and metallurgical review for final decisions.
Common questions
- What is the part distortion risk calculator for? It ranks the risk that heat treatment will move parts outside dimensional tolerance.
- What numbers should I enter? Score impact severity, likelihood, and detection risk using the same quality scale.
- How should I use the result? Use the score to decide whether to change fixturing, quench practice, stress relief, stock allowance, or inspection plan.
- When is this only an estimate? It is only an estimate because distortion depends on material, geometry, residual stress, load support, and quench conditions.
