Tolerance Stack-Up Analyzer (Worst-Case + RSS)

Mechanical engineering tolerance stack-up: worst-case (additive) and Root-Sum-Square (RSS) analysis side by side. Required for GD&T workflows and assembly tolerance verification.

How to use this tool

  1. 1

    List dimensions + tolerances

    One per line: nominal,tolerance.

  2. 2

    Pick analysis method

    Worst-case (additive) or RSS (statistical).

  3. 3

    See result

    Combined tolerance + risk vs spec.

Frequently Asked Questions

Worst-case vs RSS?
Worst-case sums all tolerances assuming everyone hits worst extreme — very safe but conservative. RSS (Root-Sum-Square) assumes random distribution — closer to reality, smaller stack. Use worst-case for safety-critical, RSS for production.
When does RSS not work?
When parts come from same batch (correlated tolerances), small sample sizes, or when distributions are non-normal. RSS assumes Gaussian + independent.
What's the 6-sigma rule?
For 99.997% yield: design for ±3σ tolerance per dimension. RSS combines these: total stack ±3σ stays within spec.

Why Use Tolerance Stack-Up Analyzer?

You should try Tolerance Stack-Up Analyzer for a quick, private way to rss + worst-case for assembly tolerance. Processing happens in your browser and files are never uploaded; the few tools that need an outside service say so on the page.

On the other hand, dedicated APIs or desktop tools suit batch processing better. They also handle server-side automation. For everyday tasks, browser tools offer the best speed, privacy, and convenience.
