Thanks for all the feedback, I have a conference call at 9 and will suggest to my customer that datum C is ambiguous and we need clarification on which feature is datum C
greenimi,
1. A-B is an axis through 2 concentric bores which is at the intersection of datum C and the horizontal centerline of the large bore
2. I interpret datum C to exist on the axis of A-B that passes through one of the M3 holes
3. Datum D exists on a face on the opposite side of the view...
KENAT, it is ambiguous and one of the small holes is on that centerline which, if you use this feature to clock datum C then everything falls into place. If you use one of the edges of the 30 degree openings then everything is skewed.
the customer is using the edge of one of the 30 degree...
3DDave, I had nothing to do with the design. This component was designed by one of my customers. They are through all of their FDA testing and are approved to start production. They are an R&D house so, they contracted another company to start manufacturing. The designer of this part is more...
It didn't like something about the original name so, I shortened it up to just 3 letters. A thousand apologies oh exalted one. I was able to open it through the link

Greetings All,
My customer is rejecting this part claiming that the lower pattern of M3 holes are out of tolerance. When I check them the worst TP I get is about .028mm they are getting TP around .380mm. When I setup and measure I'm implying the bottom surface is parallel to datum A-B not shown...
Thanks for the feedback.These parts are going to be checked by the end customer using a CMM so, I'm not sure if a template and feeler gage will cut it. This is a medical implant and they want to see as much hard data as possible. I agree that this should be controled as a profile because as it...
Hello all,
Can anyone shed some light on the feasibility of inspecting the 4.375R on the attached drawing? We have an OGP smartscope and the operator is using video and\or laser scanning to measure the radius. What I'm trying to convey to him is first, I think he should be hard probing this...
I'm just glad the lines of communication are finally open! We have a new executive VP and VP of operations now and are very receptive to people. Where in the past, if you asked for a meeting with the customer the general responce was "No, we don't want them to think we don't know what we are...
We are meeting with the customer on wednsday. I was talking with someone else about this and they made the statement that use of standards are voluntary in the US but, because my customer has referenced the standard they may be contractually bound to follow this standard. Any input on this...
Hi pmarc,
I had a chance to look at your drawing, datums P3 and P4 seem to be redundant on my drawing and datum C isn't even needed. I think I will do a redraw with a little more detail
Doug
pmarc,
thanks for the drawing let me digest it and get back to you. FYI, the .002 does apply all around (my bad) but, they have it as out bound to the profile so they can insert a cover piece to weld or braze in. The outside profile is a mess too! You have datum c from my drawing as .019...
Could someone chime in on my post where jmarc joined in? Not with respect to the messed up drawing but, to validate methodology for setting the part up to inspect with a Micro-Hite. The engineer that is in charge of the OGP claims I cannot inspect this part (with the Micro-Hite) because I cannot...
