SPC Production - Getting Cpk and Ppk

Hello to all my friends.

I need to make a control chart for analyzing (statistically) a dimension during 10 days production. I need to know the Cpk and Ppk . Does anyone have any examples please ?

Thank you

If you use the "Post attachment files" tab and type in Cpk you'll get access quite a few documents that people have posted for calculating Cpk and Ppk.
I would also recommend using the "Search ALL of Elsmar" tab and typing in "Cpk for excel" (or something like that). There are some very informative threads on the topic.

I use a Normal Probability Chart for analysis. It is easy to create and allows one to "see" the data instead of math obscuring the view.

It depends on the process, the characteristic and the specification before even pondering a chart....
