STRATEGIES FOR THE INTERVAL TOLERANCE ASSIGNING

Abstract. The strategies for tolerance design are considered, such as equal tolerance, the maximum size of tolerance field, the minimum cost and optimum price/quality ratio. Expressions for defining the optimal values of tolerance parameters are obtained. The strategy of tolerance design is selected by the normalized coefficients of strategies. The high accuracy of calculations is ensured by defining the parameters of the model at the tangency points of vertices of tolerance region with device operability region boundaries.

Keywords: interval tolerance, strategy of assigning tolerances, optimization relationship, parameter of a strategy, minimum cost, price/quality.
