Unformatted text preview: requirements. Product KCs are linked to subassembly KCs. These subassembly Manage Tolerances during Product and Process Design 61 KCs are then flowed down to Part-level KCs. Part-level KCs are critical parameters at the lowest level of the product including product features. We add a level: Design feature-level KC. These can be flowed down further to the process KCs : Intermediate Manufacturing feature-levels KCs and Manufacturing setup-levels KCs. Many layers exist within a KC flowdown. The complexity and interrelationships in a tree correspond to the complexity in the product and its manufacturing processes. Axiomatic design [Suh, 1990] provides a similar systematic method for mapping functional requirements into physical design attributes and mapping physical parameters into process variables but does not specifically focus on variation issues.
