True Position?

True Position?

True Position?

(OP)
I have three holes on a common centerline. I want to maintain a close distance to the centline with respect to each other. However, I can allow the centerline a large tolerance from the edge of the plate. If I apply a large tolerance from the centerline to the edge won't each hole be allowed to differ from the centerline by that tolerance via 14.5? How do I dimension the drawing to accomplish my goal.
Thanks
Bill

Thanks

RE: True Position?

Take a look at composite tolerancing. Specifically, Fig 5-19 and Fig 5-20 on pages 96-106 of ASME Y14.5M - 1994

Unfortunately I don't have a copy of 14.5. Can you point me to somewhere on the web I can take a look at it?
Bill

Thanks

RE: True Position?

The ASME website would be happy to set you up with your own personal copy (or company, if the case may be.)

RE: True Position?

Yeah, ASME will sell you an ASME Y14.5-2009 for $169.00, or less if you're a member. It's "spendy" as they say in Oregon and Wisconsin, but you should have one.

RE: True Position?

Thanks CheckerRon. So used to having a copy on hand, - the auxillary web references are rarely at the fingertips. One to add to that list of old designer recollections: If you're going to stay in the business, buy some tools.

RE: True Position?

Bill,

Do you have any GD&T materials on hand (books, pocket guides, etc.) ? If you do, one of us might have the same book and be able to point you to the appropriate section.

I really don't have any information in print form. I was using the site that CheckerRon listed above. It seems to have enough information there.
Thanks
Bill

Thanks
