STUDIES REGARDING THE DETERMINATION OF THE ADEQUATE ASSEMBLY TOLERANCES DEPENDING ON THE MANUFACTURING COSTS OF THE PARTS PROCESSED ON CLASSIC MACHINE TOOLS

Abstract

The paper deals with a study case regarding the determination of adequate assembly tolerances. The study concerned the assembly of two bearings on an axle. Determining the adequate tolerances of the sizes chains is based on Lagrange’s multipliers use. The optimization criterion for determining the assembly tolerances is the minimization of the product achievement cost. The relation between tolerances and cost will be revealed in a graphic component
