    Composite Tolerancing with Datums

    Hi all, On the attached drawing, I need to change the 3x to 2x since it's incorrect. But I still want to have the 0.1 lower tolerance apply to the datum C hole. How can I do this? Thanks!https://files.engineering.com/getfile.aspx?folder=8eb78bfa-ce85-4582-b4e4-44846f522f42&file=Capture.PNG

    How to Check Threaded Hole w/ RFS Requirement

    The three surfaces the holes that I'm asking about are in. It's in the drawing view I provided.

    How to Check Threaded Hole w/ RFS Requirement

    Hi pylfrm, I have attached the portion of the drawing that should clarify the requirement. Thanks!https://files.engineering.com/getfile.aspx?folder=56ffb256-a003-4346-a5fe-c9cdb991c0ae&file=Capture.PNG

    How to Check Threaded Hole w/ RFS Requirement

    Hi all, I am passing down a requirement from our customer to a supplier and it needs to match. The requirement is a threaded hole that has a true position at RFS back to a center datum hole. The supplier is unsure how to gauge this functionally via attribute check because of the RFS requirement...

    Min/Max vs. Limits vs. Plus/Minus

    My boss wants MIN/MAX, my coworkers want it removed, and i honestly dont think a makes a difference. I say "myself" because I'm trying to justify my boss's reasoning (that it drives a go/no-go gage) but I'm losing faith that it's accurate.

    Min/Max vs. Limits vs. Plus/Minus

    Hello all, There is some debate at the moment between myself and coworkers about how calling out dimensions translates into gaging. Is there really any difference at the end of the day between calling out a dimension as min/max vs. limits vs. plus/minus? I added an image just for...

    Compound Profile Tolerance with Tighter Upper Control?

    I'm having a serious brain fart on this one. I have a straight tube with two dimples in it that need to be controlled with a profile. Datum A is one end of the tube, datum B is the CL of the tube. I need to hold them to a profile of 0.5mm to datum B and 2mm to datum A, but for some reason I'm...

    Brazing 441SS to 441SS

    I see a number of high temp filler materials rated for 800°C+ so I've got to believe it's possible to find something.

    Brazing 441SS to 441SS

    Hi all, I apologize if this is the wrong subforum for this. We are brazing a 441SS bushing (4mm thick) to a 441SS pipe (1mm thick). Our company has not done brazing before and I'm having trouble finding the appropriate filler material and flux to put on the drawing. The only requirements we...

    Composite FCF with three callouts

    I'm having a tough time figuring out how best to call this out. I have three weld studs welded to a bracket. I need to control: 2.0mm perpendicularity of each stud to datum A 1.5mm TP of the stud pattern to A, B & C 0.5mm TP of the studs to one another. How can I call this out correctly? I...

    TP with or without a Diameter Symbol

    I'm looking at 7-34 and I agree that a diameter symbol would not apply here as there are two position tolerances controlling each direction. I'm in the boat where I want to call out a single position tolerance for all directions. See attached. This is where I wonder if a diameter symbol can be...

    TP with or without a Diameter Symbol

    How I've been working with GD&T for 5 years and not understood this like I thought I did is beyond me but our GD&T guru is out until next week so he cant explain it to me. Say I've got a slot with a TP of the entire feature of 0.5mm at MMC back to the datums. How is it measured differently if...

    True Position of a Feature to One Planar Datum

    Interesting. Thanks for the info on this. I learned something.

    True Position of a Feature to One Planar Datum

    Thanks for the responses. What's throwing me off is the orientation with a position tolerance. What is actually being checked for orientation here? The axis of each hole back to datum A?

    True Position of a Feature to One Planar Datum

    Looking for a sanity check here. I see this a lot and I always tell people it's wrong until today when I stumbled onto it in ASME-Y14.5M-2009. Figure 4-39 shows datum B as a feature of size with a TP back to A, which is a perpendicular plane. There's no way this can be right. Am I crazy or...
