We received a rejection stating the 12.5º was actually 10.25 degrees, they stated in the rejection the tolerance was +/- 2º. That is the UOA angular tolerance from the standard tolerance block! I don't think they know what they have drawn either! The part that makes this quite difficult is it...
This is the first time I have ever tried to post....hope it works!http://files.engineering.com/getfile.aspx?folder=090b2e19-8062-4302-8ed7-fe030ea83464&file=Angular_True_Position.pdf
There is no cad model. The pad length is given as a minimum, with the start point dimensioned at .825 +/- .040 from center of part. The 12.5º and the 120º are both basic.
The pads run from I.D. to O.D..
The 12.5 degrees is basic. The only thing I have to go on for a tolerance block is the pad callout of A|B M | Ø.030 M
with the "M's" being the max material symbol. A is the backside of the flange, B is the O.D. of the flange. The pads run from the I.D. of the part out and are spaced 120º...
I am a little stumped here. I have a part which we laser etch 3 small rectangles onto. The laser etching is called off of the centerline of the part, at 12 1/2 degrees 3 places. It has the true position box around it. The only tolerancing on the pads is a width of .120 +/- .020, and a box...
Thanks to all for the response. This is an Air Force print so the Design Engineer would not be readily available! I still thought that there was a spec out there that called it out...
Actually the issue is I am measuring a part with a callout of " sharp corner, do not deburr". I always used a .002 max edge break for a default on a sharp corner and thought there might be an actual tolerance listed in a spec.
Just started a new job and they don't have any asme / ansi specs here! Anyone tell me what tolerance I have on a sharp corner callout per ANSI Y14.5M-1982?
Does anyone have any specifications on what lab conditions I would need to accurately measure to these tolerances? I have gotten a rejection from the customer in which our parts are .0013 to .0006MM undersize. This is a tolerance area I have never been in before and do not know if I can...
Actually, I am not doing the welding, we have a welder who does work for us and my customer is requesting a spec he is certified to. I am trying to find the any specification which applies to weld repair. The material is 6061-t6
I have a part with a .125 diameter hole which breaks through and area it shouldn't. I need to do a weld repair on it and my customer needs a spec it will be done to. Any suggestions?
