The work addresses two important issues in computer-aided tolerancing: automated generation of design specific cost-to-design-tolerance models and automation of design optimization in tolerance synthesis. These are accomplished by assembling generic, production operation-based, cost-tomanufacturing-tolerance models, based upon the mechanical features of a design and their minimum-cost manufactu...

Due to the stochastic nature of manufacturing processes, the functionality of mechanical assemblies is subject to variation defined by tolerances andmanufacturing process characteristics. Inmany assemblies, functionality is also dependent on external and internal forces. Numerous Computer Aided Tolerancing (CAT) tools have been proposed that address tolerance analysis problems in complex mechan...

This vignette is intended to give a short introduction into the methods of the qualityTools package. The qualityTools package contains methods associated with the Define Measure Analyze Improve and Control (i.e. DMAIC) problem solving cycle of the Six Sigma Quality Management methodology. Usage of these methods is illustrated with the help of artificially created datasets. • Define: Pareto Char...
