First article inspection 1

[cityjack]

Morning all,

Well the design is done. Prints are made with all critical dimensions, inspection dimensions, and surface textures called out. I am trying to get a first article inspection form together for our first batch of parts to be recived here in a couple of months from the molder. I have been googling here for a while and see a whole sea of stuff. Some examples had bits and pieces I could use but nothing where I could mimic the whole thing for the most part. I am looking for a form, template, or document that will lead the mold house through exactly what I want them to do and what to pay attention to. Does anyone know of a "plastic part" specific templet at all?

Thanks

Sid

My way of dealing with noncritical dimensions is to leave them off the print.

For everything else, ... well, I never found a 'universal' First Article Report that made sense and didn't waste everyone's time. The least awful way I found of doing it is to set up a simple spreadsheet per part, with dimensions identified by description, nominal value and/or drawing coordinate location, and a small table to fill in for each such measurement on each sample in the first article lot. I usually try to flag the errant dimensions with a computed color or a computed flag like PASS|FAIL, so that whoever carries out the inspection only has to fill in the data, and does not have to make any decisions.

Thanks Mike. Makes sense to me.

When I get first piece engineering samples I just take a highlighter to the drawing and mark everything I want measured. I end up putting it into a spreadsheet with conditional formatting that flags everything out of spec and also computes min, max and average. Usually don't measure more than 6 parts on a 1st piece inspection so standard deviation is meaningless.

I've tried and tried to get the QA techs to input the data for me in a spreadsheet but other than one Thai girl who left for greener pastures, I've had no luck. I even made a template. Our QA department is wedded to creating paper documents that they continue to put in unlabeled filing cabinets that they then move to undisclosed storage locations. Then if you ask them for process capability they say they can't locate it and will have to do a study. Must be some form of job security.
