Amongst many processes existing today for the assembly of two cylindrical parts, the shrinkage fit is commonly used. However, in the calculation methods, the contact surfaces are assumed to be perfect. Therefore, in order to apply these, the standards necessitate very small geometrical tolerances. The objective of the present paper is to show that it is possible to take into account form defects by closely conformed contact modelling and to have a good representation of reality: form defects always exist to an increasing extent and are inherent in all kinds of manufacturing processes. Finally, it is shown that the presence of defects can be beneficial, allowing optimization from both a mechanical and an economical point of view.
