( I think you meant percent instead of sigma in your last paragraph though). Can Cpk be calculated for a manufacturing process before the part has even entered the sample stage? Because you know that 6 sigmas or 6 standard deviations account for nearly all eventualities on a process (assuming normal distribution) you shouldnt be surprised to see the / 3 because we are looking at only one side of the distribution. I have learned that you should calculate Cp and Cpk when your process is stable and take a production run of 30 parts without making any adjustments to the machine.

When the Cr >1, the process is not capable. If you still have trouble, email your friends attheproof@cpk.com. Because there is not a lot of historical data we take large samples from the process to account for variation. Six Sigma Process Capability & Performance Limits. Cpk is a process capability index that measures how close a process is running to its specification limits [(Upper specification Limit(USL) and Lower Specification Limit (LSL)], relative to the natural variability of the process. The Journal of Medicine and Life reports that electrocution can result in massive muscle and organ damage and even be fatal. @Ted Hessing, Could you pls share more insights into the statement where it say if Cpk= Ppk, the process is under statistical control.

A perfectly centered process a process who has a mean exactly in between the 2 specification limits (meaning halfway between the two will have a Cpk of 1. The larger the index, the less likely it is that any parameter will be outside the specification. Imagine a driver trying to park a car in a garage.
