Covers,
Anyone can share with me some samples for FAI plan's.
Do you have to include a visibility log file, correct?
what is a "visibility log file"?
We have a drawing w/ numbered dimensions, parts are measured and recorded. Record includes, numbered drawing and results and any actions taken.
We also have an spreadsheet that lists the Part Number, Rev, drawing, and results.
I don't have a sample plan to show you off hand, but MEDQA has outlined what mine used to contain.
In my own machining business (only custom parts-no off the shelf), we always forwarded First Article to customer along with the inspection report
First Article Inspections were essentially "redundant" events. The operator who made First Article would do all the measurements of characteristics according to a Control Plan previously designed and agreed to with operator, Quality department, design engineer, and customer. When done, he would find another operator to do a redundant inspection with his own (the other operator's) instruments. If there was a discrepancy between readings not accountable with "normal variation," then, and only then, would Quality department perform a third FAI. The check sheet with the results of the two operators' readings went to customer along with tagged sample. If everyone was happy with readings, production continued.
The crucial part of our practice was to "pre-agree" with the folks mentioned in the
boldface part of the quote above EXACTLY how a FAI would be performed and we would JOINTLY prepare a ballooned drawing
Courtesy of Cove member Brizilla:
a ballooned drawing is one where you number each dimension on a print and write the results on a separate numbered inspection sheet. People tend to number them and then circle each number so as not to confuse them with a number that's part of the print. Thus the "balloon".
Our check sheets would then have the dimensions numbered in the order they were to be inspected along with the type and serial number of the actual instrument used (for replication purposes) the order was to make for the most efficient inspection, often entailing using one instrument first, then moving on to next instrument. Other times, beginning with critical characteristics first so they were prominently highlighted for review.
Our "log" was critical, being able to retrieve any and all inspection sheets and instruments at a moment's notice.
The "visibility" of what we would do and did do was the entire point of FAI.
Note: the customers were happy to have the "road map" for their own inspectors, PLUS we also agreed on a similar "incoming inspection" plan (only a few critical dimensions) for the customer's sampling (if he wanted) of subsequent production shipments.
