Paper Abstract

The cost to fabricate most mechanical systems and components is in inverse proportion to the tolerances applicable. Each system performance requirement has various sensitivities to errors in certain parameters (dimensions). The total cost to produce a system is the sum of the cost of each tolerance plus certain constant factors that cannot be reduced. The performance errors of the system are the sum of the contributions of each tolerance. This paper describes a methodology that allows the designer to assign and distribute the optical/mechanical tolerances in a system to minimize the cost of production while maintaining required system performance. The practical application of this method can lead to significantly reduced cost and increased ease of manufacture without risking or sacrificing performance.
