Abstract The tolerancing of products for manufacturing is usually performed at the end design process and responsibility designer. Although components are commonly tolerated to ensure functionality, time-based influences, like wear, that occur during operation, often neglected. This could result in small amounts scrap after production, but high quantities failure operation. To overcome this iss...

This paper proposes a scheme for the tolerance specification that uses the features’ function information and mating condition attributes in the assembly to derive an appropriate tolerance specification as per the design intents. The proposed mirror method provides a way to locate the critical components. It helps the user identify functional features and group them into clusters. Temporary DRF...

The tolerancing process impacts the product quality, production cost and scrap rate. Tight tolerances allow to assure performance; loose reduce cost. tolerance allocation of a complex system is performed under uncertainty. In fact, accuracy behaviour simulation significantly affects analysis result, thus result. Therefore, method proposed perform based on Dempster Shafer theory, Monte-Carlo gen...
