Description
The first practical guide for measuring process capability in machining and assembly operations. This tells you how to correctly measure capability with all types of industrial data, including attribute and non-normally distributed variable data. This practical, on-the-job reference also provides:? Methods used to identify critical process characteristics and variables? Procedures for establishing reasonable process and machine capability goals? Steps for correctly conducting machine and process capability studies? Real-life case studies illustrate how capability indices should be calculated, analyzed, and interpreted. Confidence-bound formulas for almost every measure covered? Ways of assessing capability in special situations with tool wear, autocorrelated data, or multiple setups; short production runs, features with GD&T; parts having within piece variationIn addition, you’ll find innovative techniques by the author for measuring the combined capability of multiple processes streams, as well as that of an entire product or assembly line.Filled with more than 450 superb illustrations, this expert reference is destined to become the “bible” of capability studies, enabling you to implement the latest capability measures in any industrial setting.
