Continuous Quality Improvement in Short Run Manufacture
This paper describes an investigation into the development of a short run monitoring system. The elements of a black box feedback loop were applied as a framework to the issue of quality control. This led to the use of repeatability studies, Taguchi experiments and the application of Taguchi’s loss function. This system was developed for a use on a personal computer based in a machining cell. Dimensions were captured via digital gauges. Trials of the system have reduced output variability and the system has replaced a traditional statistical process control system that was inappropriate for short run production.
