Dimensioning Hole depth on tubing 1

[vonsteimel]

Greetings,
I was wonder how others dimension this.

Say you have 1.00 X 1.00 X 1/8 Square tubing, with a 1/4" hole in one side (but not through the opposite side).

When dimension the depth for the 1/4" hole, do you put the depth equal to the material thickness (i.e. 1/8 DP)? Or the depth to the centerline of the tube (i.e. 1/2 DP)? or some random interval that will produce the result your looking for (i.e. 1/4 DP)?

In all cases, I think the result is the same. I was just wonder what the norm was in situations like these.
Thanks,

VS

I would say "THRU ONE WALL", or give a loose tol depth.

Cut the section.

"THRU ONE WALL" would suffice with the least sheet-area req'd. A section answers it just as much, of course, but a section for every little hole can get.. messy. A standard of understanding "THRU ONE SIDE/WALL" should be acceptable. If you give them a depth to the centerline of the tube or to the /nominal/ wall thickness, some "pedantic" programmer/machinist/whatever might just cause an issue for the sake of causing an issue.

THRU ONE WALL explains the design intent while giving instruction on what the part should be, geometrically.

Or say THRU NEARSIDE.

You don't put a depth.

As others say you put a section or maybe THRU NEARSIDE or equivalent.

Thru one wall is a CAD term that I don't like but probably works.

I was only able to find mention of "THRU" in ASME Y14.6 and there it clearly meant "thru one wall" (see picture)

This is why I stand behind my suggestion - if your intent may be misinterpreted - clearly show on your drawing what you want.

 

[ewh]

Unfortunately, many of the example figures also show dimensioning hidden features.
I think that specifying "THRU ONE WALL" (which I generally use) or "THRU NEARSIDE" will suffice. You need to keep in mind, while not specified in Y14.6-2001, Y14.5-2009 ¶1.1.4 states "The figures in this Standard are intended only as illustrations to aid the user in understanding the principles and methods of dimensioning and tolerancing described in the text", and Y14.5 is part of Y14.6 (¶ 1.3).
The intent is clear and there is little chance of miss-interpreting what is required.

"Thru one wall is a CAD term that I don't like but probably works."

I've used "THRU ONE WALL" since before CAD was in widespread use.

Might be a Britishism I've hung on to.

Here in the US, we put a hole thru both walls!

I'm ready for the weekend...

It may be only intended as illustration, but it's "SIDES" not "WALLS".

CheckerHater,

Generally, I've seen/used "SIDE" when referring to a solid object and "WALL" when referring to tubing.

Tubes have walls (as evidenced by manufacturers usually calling out the WALL thickness) and solid objects have sides. Just seems more intuitive to me.

 

[ewh]

It caould be argued that there are actually four sides in that example. ;-)

[CheckerHater]

And how many walls?

 

[ewh]

2 walls 6 places

[CheckerHater]

How come square tubing has 2 walls?

 

[ewh]

It has four walls, but only two would be affected by a hole under ordinary circumstances.

[CheckerHater]

Doesn't hole in 2 walls automatically become "2 HOLES"?

 

[JNieman]

CH, I think you're over complicating the situation beyond necessity.
