Concurrent Tolerancing Design Based on Time Value of Manufacture-Quality Loss Cost

Article Preview

Abstract:

The traditional manufacturing cost-tolerance function is improved from the point of view of the time value of money, and this makes manufacturing cost in tolerances design more actual. A comprehensive mathematic model is constructed for the concurrent tolerance optimal design based on the time value of manufacture-quality loss cost. Purpose of the establishment of the model is equivalent calculation for cost-tolerance function and quality loss function of different time points, so as to make them calculated in the same time point, and concurrent tolerance optimal design is achieved. This modified model’s validity is proven by an illustrative example.
