Project PresentedProject Presented– LubricateLubricate– LoadLoad
RequirementsRequirements
CustomerCustomer– Load two types of ring sealsLoad two types of ring seals– Reject defective rings Reject defective rings – Operate at reasonable rateOperate at reasonable rate– Jam infrequentlyJam infrequently– Machine cost must be reasonableMachine cost must be reasonable
EngineeringEngineering– Quantifies customer requirementsQuantifies customer requirements
TargetsTargets
