Abstract:

Equations that provide approximate but highly accurate lower confidence limits on process capability indices are provided. These equations yield the same value to the nearest hundredth or better than the values provided in tables in the literature. These equations can be used for a much more extensive set of data than those of the existing set of tables. Quality control, Process capability, Confidence limit.
