There is nothing inherently wrong with the drawing you provided except for the placement of your feature control frame for the position of the 4.137 diameter. Whether datum feature A or B should be the primary datum depends on function of the part. If the orientation to datum feature A is most...
Just a side note: The thread call out is for a UNF thread however the spec (MIL-S-8879 currently AS8879)and the minor diameter listed is for a UNJ thread form.
Thank you for the comments, my understanding based on the comments is: the runout would control the form of the spherical radius and would control the location in relation to the datum axis but not the distance from the face (datum feature A).
I have additional questions:
1. If the distance...
chez311,
Thank you sir. The examples sited where very helpful. The only thing I'm not clear on is the distance from the face (1.00 basic) controlled using total runout? Figure 4-21(b)would indicate that it is.
Total run-out interpretation.
I’ve been lurking on this forum for several months and I am impressed with the wealth of knowledge the members bring to the forum. My understanding of the standard has grown as a result. The standard I am referencing in the example is the ASME-Y14.5-2009. For...
ASTM E-29-13 (Standard Practice for
Using Significant Digits in Test Data to Determine
Conformance with Specifications) describes two methods of rounding data.
AMS 4120 covers bars, rods and wire. Bars can come in many shapes, round and hexagonal being two of them. Round bar would meet the AMS 4120 requirement. Typically the hex size and tolerance should be listed but absent the tolerance I would default to ANSI H35.2 (dimension and tolerances for...
