Document Summary
The costs of finding and correcting a defect increases by a factor of 10 as products move through major manufacturing stages to the customer. R&r r&r study is done to know the accuracy and precision of our gauge: keeping in mind, 100% inspection is at best only able to find 80% of defects . If the % defective is greater than the break even point, 100% inspection is used. Bias = how accurate is our gauge to a reference value? . Linearity = does the bias remain constant over the measurement range? . Cost of quality across manufacturing steps & design for manufacturability. The cost of quality is largely determined by design: by failing to integrate manufacturability into design ongoing production & service costs increase. 2- cqa"s are features when controlled within defined limit, range, or distribution ensure. Variability has an impact on a cqa.
