First post - please be gentle.
I work for a major UK OEM who runs Ford based APQP/PPAP systems. We use a PPAP check list based on a Ford document. One of the questions under 'Initial Process studies' section reads:
"Was a statistical software calibration, using the Sample Calibration File conducted?"
I've asked around (my organisation) within STA and Six Sigma communities to a senior level. Nobody is able to provide me with a "sample calibration file". I've looked through the AIAG SPC (2nd Ed) & PPAP (4th Ed) manuals and can't find any referance to statistical software calibration. Not even Google can help. My Manager suggested I try asking on Elsmar Cove.
Can anybody shed light on this? Idealy I'm looking for a copy of a/the "sample calibration file" and instructions how to use it to perform a statistical software calibration.
I'm asuming it's just a data set, with verified statistical properties, which can be used to check the output of suppliers spc spreadsheets.
Any help greatfully recieved.
Thanks,
Andy Skelton
