Concurrent process tolerance allocation of mechanical assemblies mainly focuses on concurrent allocation of dimensional tolerances, less consideration of geometric tolerances. The goal of this paper is to extend the concurrent tolerancing model to realize concurrent allocation considering both dimensional and geometrical tolerances. The proposed model simultaneously allocates process tolerances based on the minimum of the summation of expected quality loss and manufacturing cost, in which the geometrical tolerances are either converted into equivalent dimensional tolerances or only treated as additional process constraints. The validity of the model was verified by an example of wheel assembly.
