Number of people, who does it, and are they dedicated blue printers or people doing this as one of several duties?
Environment:
We don't do design work and we do not produce original blueprints. We receive customer prints dimensioned and toleranced as they have it.
We produce a "re-print" for our shop that may have some dimensions re-toleranced for production purposes. For instance: Overall lengths may be stated by the customer at the Low, tolerance -0 / +.0005. Our reprint will have that dimension at the high to -.0005.
In another case you may have a dimension like an OD at .5000 -.0005 / -.001, and the shop foreman may reprint that DIM as .4995 +0 / -.0005.
We have a two-person dynamic in place:
Shop foreman takes prints from customer service, reviews the job and produces a reprint. I get the job packet and run a basic check of the elements using the customer blueprint & sometimes the 3D if necessary.
Mistakes are still slipping through the both of us. Not often, but it happens periodically. Usually simple eyeball errors like what was supposed to be a .4995 +0 / -.0005 actually stated as .4955 +0 / -.0005. I'm sure when I was checking the blueprint I "saw" .4995 on our reprint when what was actually there was .4955. So the reprint from person 1 put the wrong DIM, and person 2 didn't catch that error either.
The first obvious answer is "pay attention, don't be distracted, stay focused". And that's the right advice. Yet, periodic misses are still occurring between two people, one of whom has 35 years machining experience.
So I'm looking to switch up some dynamics if I can figure something out. The two of us deal with the blueprints amidst other duties (not dedicated blueprinters), etc.
My point in coming here with this question was to simply sonar-ping what you do, how many people are involved, and specific notation methods employed in the process.
Thanks in advance.
