Rectangular Tolerance zones
Rectangular Tolerance zones
(OP)
This thread was started so as not to hijack the "Symmetrical" thread any more than it already has been.
Regarding ringmans reference to FIG 5-21 in the standard, I have no idea what you are trying to convey about rectangular tolerance zones by using this example. This is a perfect example of cylindrical tolerance zones and their application as well as composite tolerance frames and how coordinate tolerancing can't address it.

RE: Rectangular Tolerance zones
First of all thank you for your service to the U.S.A. as well as any veterans reading this post. With that said, I understand your rant concerning the lack of GD&T. This is my second year in the industry so I might not have developed the hindsight to make the following statement or rant if you will. It seems my company doesn't employ GD&T because of a desire for short-term gain and never learning from long-term loss. It is well-known a lot manufacturing is being sent overseas and the constant pressure to keep part cost lean. Upper management fears the datum symbols, so displaying 2 FCFs would warrant public ridicule to shame one from stepping out of the coordinate zone. Upper management is stellar when it comes to multiplying annual consumption x increased costs for accuracy. The short-term cost savings are great until your MRB queue becomes overflowing.

My thanks also to you and all the others involved in Iraq and Afghanistan. Our hearts and prayers go out to you.

thread1103-192933: GD&T part costing more
The more I get to understand GD&T the more I think it adds value. However, I also become aware of how ignorant (sounds a bit harsh but hopefully you know what I mean) a lot of people are about GD&T. What's the point in essentially defining a 'common language' if 80% or people that should be using it don't learn it.
I'm not an expert but am doing the best with the resources available to me.

RE: Rectangular Tolerance zones
I do believe there are applications for square zones when using positional but from my limited experience diametric is more common.
(last post should have been 'best I can'.)
