Geometrical robustness analysis considering manual assembly complexity
Paper in proceedings, 2014

The manufacturing industry is focused on geometry assurance. Much of the virtual geometry assurance is done in Computer Aided Tolerancing (CAT) tools. Earlier research shows that assembly complexity influences the product quality but is not considered when geometry systems (locators and tolerances) are defined. Further previous research shows CAT simulations do not predict all the variation and therefore additional factors need to be included to improve accuracy. In this study, a robustness value for a geometry system solution based both on geometrical sensitivity and manual assembly complexity has been introduced. Calculation methods have been tested and implemented in a CAT tool using a real industrial case.
