Variability is unavoidable in the realization of products. While design must specify ideal
geometry, it shall also describe limits of variability (tolerances) that must be met in order to …

Tolerance analysis aims at predicting the effects of inevitable geometric deviations on the
quality and function of mechanical products and is therefore an import tool in the design and …

With the introduction of new technologies, the scope of miniaturization has broadened. The
conditions under which complicated products are designed, manufactured, and assembled …

Simulative gear rolling enables the integration of function-oriented quality assurance into
production processes for Zero Defect Manufacturing (ZDM). A simulated single flank rolling …

Companies are confronted with increasing product quality requirements to manufacture high
quality products, close to technological limits, in an economic way. The implementation of …

In this paper, an original equivalent mechanism with parallel linkages is proposed for lost
motion behavior analysis and tolerance synthesis of planetary gear train (PGT). The parallel …

This paper presents a new approach to the tolerance synthesis of the component parts of
assemblies by simultaneously optimizing three manufacturing parameters: manufacturing …

The ongoing research is hard to predict the machining accuracy of machine tools in the
preliminary design phase. Hence, a rapid and quantitative prediction method seems very …

In manufacturing companies, assembly is an essential process to obtain the final product.
The life cycle of an assembly product depends on various production strategies, eg …

Many tolerancing problems on mechanical assemblies involve a functional requirement
depending on a chain of parallel dimensions on individual parts. In these one-dimensional …
