Abstract

It is demonstrated that a dependent dimension in assembly, indicated according to the classical dimensioning rules, is not uniquely defined. It is shown that if parts in assembly are defined by the vectorial dimensioning and tolerancing, VDT, then unique specification and verification of the analysed functional dimension in assembly is assured. The stackup of location and orientation vectors on the case of an assembly shaft– sleeve–plate based on experiments carried on coordinate measuring machine, CMM, is analysed.
