JNieman, do you have other link? That link is not working. And so what is the F3 break?

Belanger : so which value should I report? The envelope or local value? Thanks!

pylfrm, the tolerance is +/-.005". The print callout to inspect and report this dimension.

Thanks Belanger! I am having problem of expressing.

Thanks for the feedback. Refer back to the standard and comments, to my understanding, it seems "X" measurement is the correct approach, because it covers the form and size. But according to Belanger, it is not right. What had I interpret wrong? Please help.

Just want to clarify, the measurement will be carry out certain places and obtain the average or highest value. It is a requested inspection dimension, no actual mating envelop is given.

Using standard ASME Y14.5M. So I have a drawing callout for dimension inspection 2.000". This part is, let say, its round. How should I measure this part? --X is having the part sitting on a surface plate, then using the height gage or CMM to measure the value. Origin value is reference to the...

I understand the three lobes. The diameter was measured 12 points, uniformly distributed, using CMM. I hope I interpreted correct: It seems for me that the diameter 10.003 is an average value. Roundness represents this result's bilateral tolerance. I think I badly worded this subject...

As I know it use LSQ-->Least square method. So the number of the diameter is average?

ASME. But is my interpretation correct? -->that mean the diameter is the average result and the actual size become 10.003 +/-.0055?

Oh, I understand the roundness should be within size tolerance. I want to know how does the roundness "calculated" or obtained. In addition, is that mean the diameter is the average result and the actual size become 10.003 +/-.0055?

For example: The drawing callout of the part has a diameter of 10.000 +/-.005" Using CMM to measure this part: Diameter 10.003" Roundness is .011". Does anybody know how these number formulate?

Vishal2015 (Mechanical): What does it mean by 'Straightness is maintained in X and Y Direction in zero'?

3DDave (Aerospace): Link is not working...I would like to read it. :) Thanks!

Guys, Thanks! Yes, the reflected question comes with a roundness of .060", call out as follow: Diam. 14.000 AVG [O|.060(F)] Default tolerance is +/- .005" Using ASME Y14.5M-1994/2004. 3DDave: I just want to clarify that the section that I mean is let say I have a 1" height with 14" diameter...
