Engineers involved in casting a machine bracket designed a Taguchi experimental study to improve the process and reduce the scrap rate. As a result of the study, a number of improvements were incorporated. Data were taken from 10 samples before and after the manufacturing improvements. The foundry had a production rate of 1500 castings per month. The quality inspection criterion was a length dimension of 120.35 inches. The parts that did not fall within the limits were rejected. The average unit cost for scrap or rework of the rejects was $20.
