    DATUM REF 5 DEGREES OF FREDOM

    My initial question was it is possible to create a Datum Reference Frame (DRF) with only A and B for my assembled As the example.

    DATUM REF 5 DEGREES OF FREDOM

    I know that, concerning the Slot. My question is, it is possible to take the hole + the slot to create a DATUM REF. Like to if you have 4 holes together. As Shown in the linkhttps://files.engineering.com/getfile.aspx?folder=8d4405a8-e89d-4b5c-954b-fbfd8c16ee86&file=fig_7_18.png

    DATUM REF 5 DEGREES OF FREDOM

    it is possible to create a DATUM REF with 1 slot & 1 holes together to remove the 5 degrees of freedom. DATUM REF B in the figure linkedhttps://files.engineering.com/getfile.aspx?folder=83946eaf-0606-4cd6-a99b-6db0107a21ab&file=5_degrees_3.png

    Aligment

    All of the problem is here. If I consider the tolerance zone let a cylinder, it will be neccessar to use the option with the symbol of POSITION. But as I explain on my picture, this solution is used only for the coaxiality between a shafts. It's true? isn't it. Or, is it possible to place a...

    How to interpret those dimensions ?

    The figures in the ASME Standard are intended only as illustrations to aid the user in understanding the practices described in the text. See § 1.4.8 of ASME Y14.5 2018. We see in each technical point the picture associated in this form for exemple (fig.21) . Second point, when you read a...

    Aligment

    Let's assume that we have 3 same parts (pie form) should be placed on upper level with each vertex of angles on the same axis but not at the same depth. Can you help me to show the better way to define that on a drawing. I do 2 exemple, perhaps you have a better than me. Of course I've voluntary...

    digits on basic dim and the tolerance

    So, to limit the waste of parts that could be good it is better to review the information on the drawing because a control for 0.1 is done by caliper while for 0.001 you need a specific control tool.

    digits on basic dim and the tolerance

    ] To me there is a difference. +/- 0.1 can be inspected by a caliper and +/-0.10000 needs a control tool much more accurate. So more expensive. And if I go in the direction, and I note as value on my coin 0.1003. What do I deduce from this? While it is not requested on the drawing.

    digits on basic dim and the tolerance

    I will ask my question differently. On a drawing there is this information. 15.236 +/- 0.1 Does this bother anyone? Why indicate an accuracy of .236 on the dimension, when the tolerance requires .1

    digits on basic dim and the tolerance

    This explains to means the possibility (to think) to add a ZERO(S) after the last character. My problem is not the number of ZERO, it's there is a value non-zero on second position after the dot on the Dimension and just one in the tolerance.

    digits on basic dim and the tolerance

    I would say that the 0.05 mm (5 hundredth) is not "serious" since the tolerance is at the tenth (0.6)
  13. nry67

    digits on basic dim and the tolerance

    Yes, I agree for the value of tolerance, but remove the second digit after the dot in the dimension, wouldn't that be fairer?

    digits on basic dim and the tolerance

    I'm sorry but I must be expressing myself badly. I summarize. On a drawing I have the information above. My doubt is to write 25.75 and not 25.7 which for me is altogether more logical given that the value in the control frame is 0.6 Am I right in saying this? I'm agree with 3DDave "the...
