Abstract: Most researches of tolerance design focus on the detailed design. Tolerance design during early stages of design will lessen design modifications and shorten its period. A new method is presented to study the tolerance in the conceptual design based on the growth design. First, the basic concepts and the principles of the growth design are explained. Then the process model of tolerance synchronous synthesis is built. The local dimension chain and overall dimension chain are set up automatically. The whole frame of tolerance design and relevant feeding back is established. The tolerance design of piston clamp is carried out by the application of this methodology.
Key words: Tolerance Growth design Functional surface
