Industry is facing the management of geometrical deviations along the entire lifecycle of the
product. It is helped by digital twin tools that may minimise the geometrical deviations from …

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 …

Geometrical variation in individual manufacturing and assembly processes often propagates
and accumulates, resulting in products that do not fulfil functional, esthetical or assembly …

Weight reduction requirements in aerospace and automotive industry lead to an increased
use of composite materials. However, composite parts cannot be bent like sheet metal parts …

Geometrical variation and deviation in all the manufacturing processes affect the quality of
the final product. Therefore, geometry assurance is an important tool in the design phase of …

Composite structures play an important role in realising resource-efficient products. Their
high lightweight potential and improved manufacturing technologies lead to an increased …

The application of an interference fit in the assembly process of thin-walled aerospace
composite parts is prone to stress stiffness effects, namely the structural stiffness change …

Many research works on tolerance analysis have been carried out in the last thirty years. In
this paper, a new idea is proposed, aiming to investigate the effect of form error and …

Overconstrained assemblies such as aircraft sub-assemblies present a challenge to
production planners, as variations in parts and processes can make it difficult to achieve all …

In the last 30 years, many research works were carried out on the tolerance analysis.
Historically, tolerance analysis of rigid assemblies was always separated by that of …
