Calculator Exclusive — Tolerance Stack Up
Assumes a normal distribution of parts. This is more realistic for high-volume manufacturing and allows for looser, cheaper tolerances while maintaining quality. 2. Sensitivity Analysis
High-end tolerance stack-up analysis tools often leverage automated 1D, 2D, or 3D modeling, with solutions like Enventive and CETOL 6σ, or CAD-integrated tools like SOLIDWORKS TolAnalyst, being top industry choices. Effective analysis requires supporting multiple methodologies, including worst-case analysis, Root-Sum-Squares (RSS), and Monte Carlo simulations to ensure manufacturing quality.
