An optimization model has been built with consideration of required reliability, minimum machining cost and quality loss. The normal and the lognormal distributions of the tolerances that depend on the production types of components are used in the reliability model. Cost-tolerance data obtained from Bjorke is used to calculate the machining cost. The asymmetric quadratic quality loss model is used to calculate the quality loss caused by the deviation and the mean-shift of distributions. The tolerance allocation of a sliding vane compressor is optimized for reliability, cost and quality loss, and the optimum tolerances of components are recommended. The results show that high accuracies of the slot length, the vane thickness and the slot width are required. Hence, their tolerances are smaller than other components. If the correlation coefficient of the bottom cover plate and the top cover plate and the correlation coefficient of the front cover plate and the rear cover plate are equal, the effect of correlation coefficients on the cost is insignificant.Copyright © 2004 by ASME
