Tolerance design improvement of mechanical assemblies through tolerance analysis and optimization

Abstract

Tolerancing is a key technique in CADCAM integration It utilizesthe required functional characteristics and manufacturing cost of the product newlinewhich have a great impact on determination of the process method machinetooling setup and process sequence of the part in the processing plan In newlinemechanical design geometric and dimensional tolerances are used to specifythe range within which a part geometry and size may vary while conforming newlineto the functional requirements Assigned tolerances have a direct effect notonly on the machining costs but also on the product quality Unnecessarily newlinetight tolerances result in high production costs yet the tolerances should newlineensure that the functional performance requirements of the products staywithin a satisfactory range newline newline
