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
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...
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...
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...
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...
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...
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...
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...
