COST OPTIMISATION FOR ASSIGNED TOLERANCE TO A 2D DIMENSIONAL CHAIN USING GeoGebra SOFTWARE

Aurel TULCAN, Felicia Veronica BANCIU, Ion GROZAV

Abstract


The analysis and allocation of dimensional tolerances is still an important subject because the closing dimensions of dimensional chains (LDs) have to meet the design requirements, respectively fall within the desired tolerance range in order to support the products quality requirements. This paper presents an initial analysis of a chain of 2D dimensions, next the tolerance fields of the 2D chain dimensions will be reallocated according to a transfer coefficient in relation to the closing dimension of 2D chain while minimizing the cost of these tolerance fields. To minimize the costs, the variation curves of the tolerance costs were used and finally, the assigned tolerances are verified using the Monte-Carlo method.
