Tolerance Analysis CASE STUDIES

Tolerance analysis on Emax 2 low voltage air circuit-breakers series

ABB SACE

Through the CETOL 6σ analysis of the propagation of the tolerances within the dimensional chain it has been possible to identify the dimensions and tolerances with the major impact on the functional measurements and therefore to act in a targeted way for the resolution of potential non-compliances, avoiding the generalization of their treatment. READ MORE…

Tolerance Analysis WHITE PAPERS

UNDERSTANDING STATISTICAL TOLERANCE ANALYSIS

A statistical tolerance analysis is when you take a set of variance inputs to calculate variation on the desired output. In mechanical engineering,
this is done when you have multiple features, each with tolerance values and an analysis is performed for the entire assembly. In mechanical design, certain performance characteristics are typically the result of the dimensions on the individual parts. READ MORE…

 


MONTE CARLO WHITE PAPER

This paper explores a new second-order tolerance analysis (SOTA) method, the development of which was motivated by the differences in capabilities between the Linearized Method and Monte Carlo simulation of tolerance analysis. READ MORE…

 


FUNCTIONAL INTERFACE-BASED ASSEMBLY MODELING

The continuing market pressures for development and delivery of new products faster, cheaper, and at higher quality are driving the need for assembly models that not only provide information regarding both design and manufacturing issues. This paper presents two key aspects of an approach to assembly modeling that will support the extended challenges of today’s design and manufacturing environments. READ MORE…

 


TOLERANCE STACK-UP
