EZtol

The 1D tolerance stack up analysis tool

EZtol

EZtol is a product of Sigmetrix LLC.

EZtol is a 1-Dimensional tolerance stackup analysis program designed to assist in understanding the impact of the accumulation of part-level dimensional variation and part-to-part assembly variation sources and the impact that they have on assembly-level requirements.

Today such analyses are performed in a spreadsheet, most commonly Microsoft® Excel®. Much work is required in creating spreadsheets that manage all of the product requirements simultaneously with consideration of common dimensions and tolerances that feed each one, properly including the impacts of the more complex geometric tolerances, and properly calculating the statistical results. Analysis spreadsheets often include a visual diagram either from the model or an assembly-level drawing to help explain the components of each of the analyses, but these too must be maintained as updates are made.

Key features of EZtol - Summary table and visual indication on meeting requirements - Dimensions and tolerances are stored for each part allow for efficient automatic analysis updates - Detailed report generation with graphical views

L’analisi delle catene delle tolleranze

Da nemico ad alleato

Per analisi delle tolleranze si intende una metodologia che si utilizza nella progettazione di un prodotto, per comprendere come le imperfezioni di parti, in fase di fabbricazione, e di prodotti, in fase di assemblaggio, influenzino la capacità di un prodotto finito di soddisfare le aspettative e le richieste del cliente.
Scopri come EZtol sia lo strumento indispensabile per comprendere l’impatto dell’accumulo di variazioni dimensionali e geometriche sui requisiti delle parti e dell’assieme in modo semplice, efficiente e veloce.
