I need help on how to inspect the 5 different dimensions in the attached drawing using an optical comparator with a Micro Vu Q16 processor. Any advice would be greatly appreciated.

Usually, when I see that many basic dimensions, there is a profile called out somewhere. If it is a MMC profile, then I would use a template. All I saw was the true position for the hole, but that can not be all, I am thinking....:cool:

I don't see a "B" datum, nor any feature control for any of the basic dimensions (other than the position callout for two holes).

You are correct there is a profile of a surface callout, "profile of a surface to be within .030" RFS relative to datums A, B, C RFS".

Datum "B" is the small hole in the middle and datum "C" is the bottom hole.

I didn't realize they were missing, sorry...

Ouch! RFS! Better bring in the pros for that one...:cool:

A few questions....


Datum feature "B" is a feature of size (HOLE); is it called out at RFS as well?
Based on the datum feature symbol, I concluded that the drawing is the ANSI Y14,5M-1982 version, is that correct?
Is the "profile of a surface" callout specified as "all around?"
Can you show us the actual drawing?

Stijloor.

Stijloor, I have attached the majority of the actual print. Any further help would be appreciated.

You are correct.
