【Abstract】 Relationships between quality loss and product’s sized tolerances are studied.Quality loss of a product with multiple correlated assembly dimensions is proposed and expressed as a function of the related process tolerances.Concurrent tolerancing optimization model is proposed to implement concurrent tolerance design for a product with multiple correlated assembly dimensions by using cost-tolerance function and quality loss.A practical example is also introduced to validate the proposed method.更多还原
