Starting to get Involved
Hi all,
New to the forum!
Hopefully you can help.
Currently validating a CNC process. Have competed prelimary capability studies based on 3 batches of 50 parts. Have got good cpk and ppk vales for the process (all above 2.57).
We are hoping to start validation of the process next week. All protocols are compete.
Problem is that we have in process inspection sheets (1 in 30 parts), however once the process is up and running we hope to run unmanned for up to 3 hours (100 parts).
I presume we need to validate based on an inspection frequency of 100 parts ? But we are currently not sure that we will be able to run for this period of time unmanned (based on 50 parts it looks good).
My question, Can we validate the process and ignore the in process inspection data for the moment? And when we do run the 3 batches of 250 parts for validation and prove capability over X number of part finalise our in process inspection sheets at this point instead?
Basically, will finalising our in process inspection sheets after validation as opposed to before validation void our validation effort?
Hope you can help!!
Many thanks
