Tolerancing is commonly performed in late design stages, in which the product geometry is
fully defined. However, this often leads to high manufacturing costs or expensive design …

Geometric dimensioning and tolerancing (GD&T) tolerance standards are widely used in
industries across the world. A mathematical model to formulate tolerance specifications to …

Tolerance analysis is frequently used in predicting the product quality and balancing the
design tolerances in mechanical assemblies. Generally, the tolerance analysis procedure is …

One of the most influential causes of dimensional inaccuracy in automotive bodies is the
inescapable fixture deviation, which is propagated in a Multi-Station Assembly (MSA) …

Purpose Manufacturing errors, which will propagate along the assembly process, are
inevitable and difficult to analyze for complex products, such as aircraft. To realize the goal …

Tolerance allocation is an important step in the design process. It is necessary to produce
high quality components cost-effectively. However, the process of allocating tolerances can …
