Tolerance Stack-Up Calculator

Estimate how multiple dimensions accumulate in a one-dimensional assembly stack. The calculator reports nominal total, worst-case min/max, and RSS tolerance from four contributors with symmetric plus/minus tolerances. It is intended for early design and manufacturing discussions, not full GD&T analysis.

Cómo usar

  1. 1Enter nominal size and bilateral tolerance for each contributor.
  2. 2Review nominal total and worst-case envelope.
  3. 3Compare the RSS estimate if your team uses a statistical screening approach.
  4. 4Document assumptions before using results in release decisions.

Preguntas frecuentes

Does this support asymmetric tolerances?
Not in this UI. It assumes symmetric plus/minus tolerances.
Is RSS safe for production release?
Only if your organization accepts the underlying statistical assumptions and process capability basis.
