SPC Light Program - Easy way of Cpk extraction from multiple control charts

[nihanc]

We use SPC light program at our shopfloor. I could not find any easy way to download cpk values from diffent charts as a summary or report. In order to follow up cpk trend from week to week, somebody needs to sit down and write the cpks from individual charts. I hope there is another logical way I am currently missing. Any help appreciated.

I assume that you're using an SPC software program? Have you discussed this with the software vendor? Also, you IT folks may be able to help you.

what is the purpose of having someone to sit down and write the cpks from individual charts from week to week to follow up cpk trend?

production operators need to obey rules of SPC but sometimes quality and manufacturing engineering( owner of the process) would like to review the long term capability .To have data for that review, we could not find an easy way.
In fact from CMM ( ZEISS) to SPC Light we have automatic transfer of the sample meaasurements. We have gained value added time there , but we have this problem and it is completely waste AS you are questioning!

If you will post or send me the data the SPC data that you wish to examine, I will put it in a format which was proposed by Art Bender (a founder of ASQ). It is very visual and can describe what is happening to the process to all.
