Question: A process is currently producing a part with the following specifications: LSL = 9 and USL 28 inches. What should be the standard deviation (sigma)
A process is currently producing a part with the following specifications: LSL = 9 and USL 28 inches. What should be the standard deviation (sigma) of the process (in inch) in order to to achieve a +-6Sigma level production?
A product has 5 components and each component has one CTQ. Quality level of all CTQ's are at +-3Sigma. What percentage of the products produced are non-defective (conforming)?
| Consider the manufacturing of a 3D-printed complex mechanical part. Production rate is 1000 parts per day. The process has a first-pass yield of about 61 %. About 31 % of fallout can be reworked into an acceptable part. What is the manufacturing cost (in $) per good part produced if direct manufacturing cost per part is $50.00, with an additional $10.00 for rework? |
