Repeatability synthesis methodology for modular ultra-precision assembly systems

Many assembled products have ever shorter lifecycles while the demand for ultra-precision continuously increases. Modular assembly systems are design to address the need for volume and product variations and need to increasingly address demand for higher accuracy and repeatability. This paper proposes a new methodology for the repeatability synthesis of modular assembly workstations based on the basic characteristics of their modules. The methodology simultaneously takes the physical configuration of the modules and the process setup of their skills into consideration.
