Computer Aided Machine Qualification

This article concerns the process of conducting a machine qualification (or process capability) study. It presents the results of a research project undertaken to investigate the shortcomings inherent in the typical team approach to machine qualification, and to design a comprehensive computer system to overcome these shortcomings. The article begins with a discussion of the steps involved in a qualification study, pointing out that inefficiencies and inaccuracies often arise due to the heavy time and statistical burden placed on the study team. The functionality and the features of the PC‐based computer system developed in the research are described. Numerous screens are provided to illustrate these features. Finally, a synopsis is given of the primary benefits of the system, as well as its limitations.
