Abstract:

Starting from the idea that prescribing larger tolerances for product design leads to reduced development and recycling costs, this paper presents a virtual tool made in LabVIEW that can be used by designers and technologists to interpret and implement precision prescriptions of the macro-geometric form based on size - dependent tolerances, respectively based on the principle of maximum material and the envelope requirement. For completing the programming algorithm there were estabished the dependence relationships between straightness size-dependent tolerances, straightness tolerances inscribed in drowins and the actual dimension of the tolerated surface. The work will continue with the making of other applications regarding prescribing precision to the relative position based on size-dependent tolerances.
