Just because you teach it doesn't mean you can do it.
Getting folks out the door with the wrong terminology is a disservice.
Hey I didn't write the stuff it's under the standard. So you have all these books that are about GD&T. But the specification ASME..2009 dosen't change. Thanks for...
Okay ASME Y14.5 2009. I think that is stated on the drawing as well. Happy now?
With Datum feature C being referenced there is no way the 1st 2nd and 3rd planes of the datum reference frame can rotate or shift. So what does that mean? the part on the inspection table cannot move around based...
So to answer my own question Datum feature C can be used as a third reference for clocking. Correct it's not needed for people that don't know what they're talking about. Who use incorrect terminology.
Datum features are not datums. A datum is a letter in a square box. You never dim. Out to a...
No -- again -- do not use datum C in this drawing. Why does it matter if the part spins around 360º? The position of the holes are NOT being checked for rotation on the part. They are only checked for rotation relative to each other (which is the point that SeasonLee and 3DDave were making)...
Datum features are not datums. Datum features are not datums. Please show me your resource that allows you to say datums. When using a standard like ASME Y14.5 from 1994 through 2009.
Please!!!!!!! Show me where it says!!!!! Datums... positional tolerance frames reference the datum features on...
Lastly datum planes simply do not exist. The term you want to use is called datum features. Datum features are not Datums. The datum planes we refer to only exist in the machining equipment.
Belanger. Yes that was the answer I was looking for. Some what.
To truly lock down the whole part on the inspection stand. Was to elimanate any other movement because Datum feature B is only two points of contact. Someone were to bump into the table this thing has the potential to move. In...
Please see attachment and comment your verified thoughts.http://files.engineering.com/getfile.aspx?folder=f63c8a02-2146-432c-9216-74a4b5c4e70c&file=THOUGHT_SO.PDF
Decimal equivalency. This is not about metric values and the order of magnitude.
This is about inches and its decimal equivalency in regards to hole size and positional tolerance.
If you have to I’ll state using ASME Y14.5 2009.
Does anyone practice or does it matter? By matter I mean “what...
Whats up guys. How should I get started on creating a tire pattern on Solidworks? I have no clue where to begin. What facts to remember when creating this pattern around a circular object feature. Anyone know how I should begin.
I want to be able to model a bicycle or wheel including the rims in...
I'm pretty consistent on drawing layouts (i.e. format: Note callout, Hole callout, Dimensioning to the best
features and between views). One thing I never got a handle on was using TYP, 3 Places, as oppose to 2X or 4X.
Lets say a square part has a dim. that is 2.00 long. I use 2X, 2.00 As oppose...
A great use of experience answered my question. Thanks guys. I knew
that Runout or Total Runout cannot be used on a threaded integral stud.
Or an internal thread say 2 1/4 size in a circular part. I work with some old
school prints and co-workers who may have heard or read GD & T and...
Maybe check a Jr. college who has an
Aerospace influence from a big name OEM.
There maybe a good chance that e-bay will
have some DVD's that self teaches you.
Questions for GD&T'ers: Can runout or
total runout be applied to Threads (external or internal). My GD&T books only shows examples to Circular surfaces O.D.'s
