    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!

    Dimension Inspection

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

    Thanks Belanger! I am having problem of expressing.

    Dimension Inspection

    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.

    Dimension Inspection

    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.

    Dimension Inspection

    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...

    Formulate Diameter and Roundness

    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...

    Formulate Diameter and Roundness

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

    Formulate Diameter and Roundness

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

    Formulate Diameter and Roundness

    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?

    Formulate Diameter and Roundness

    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?

    In worst case, the flatness is...

    Diameter AVG explanation

    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...

    Diameter AVG explanation

    snap shot about the AVG.http://files.engineering.com/getfile.aspx?folder=1328097c-a522-44c9-9e38-40204ea081b8&file=Diameter-AVG.JPG

    Diameter AVG explanation

    I am confuse about this AVG explanation. Would like someone help to clarify. Let say I have a cylindrical part. The diameter comes with AVG notation at side. Does this mean that it is require to measure the diameter at least at four different sections and get the average result? If yes, if one...

    High Temp Caster

    I did try that. But the temperature does not meet.

    High Temp Caster

    I am looking for caster, most likely to be stainless and will be used in high temperature, about 280-450C. It should handle at least 200lb per caster. As I know most caster come with greased, or plain bearing. This specific caster should not have grease, no bronze filling. Do you know where to...

    Size tolerance

    Size tolerance: part measure from a flat surface (I am indicating the height of a part). Is this a correct statement? How about thickness of a part?
