How do you convert DPMO to Sigma Level? There are several metrics you can use to measure how well your process is performing. Let’s look at three of them and discuss how to calculate them and how they ...

Process capability indices (PCIs) have long served as crucial metrics in assessing the performance and quality of manufacturing processes. Recent advances in statistical estimation techniques have not ...

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 ...

If you do not specify both LSL and USL, the variable _CP_ is assigned a missing value. The process capability index C pk is computed as If you specify only USL, the index C pk is computed as You can ...

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 ...

Repeatability means the ability to produce parts that have identical properties. As with other manufacturing processes, this capability is very important in injection molding because it has a crucial ...
