Automotive manufacturers are improving quality control by applying precise metrics like Cp, Cpk, and GR&R to track process capability and measurement accuracy. Combined with structured improvement ...

When holes produced satisfactorily on lathes suddenly have to meet a process capability of 1.67 or 2.0 Cpk, turning operations may fall short. That capability requires a process that makes it easy to ...

In this example, the capability index C pk is computed for the amplification data in AMPS. To examine the accuracy of this estimate, the following statements calculate a 90% confidence interval for C ...

In Figure 1.2, the table labeled Specification Limits lists the specification limits and target value, together with the percents of observations outside and between the limits. The table labeled ...
