Dimensioning Hole depth on tubing

Dimensioning Hole depth on tubing

Dimensioning Hole depth on tubing

(OP)
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

RE: Dimensioning Hole depth on tubing

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

Cut the section.

RE: Dimensioning Hole depth on tubing

"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.

RE: Dimensioning Hole depth on tubing

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.

RE: Dimensioning Hole depth on tubing

"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.

RE: Dimensioning Hole depth on tubing

Here in the US, we put a hole thru both 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.

RE: Dimensioning Hole depth on tubing

It caould be argued that there are actually four sides in that example. winky smile

RE: Dimensioning Hole depth on tubing

And how many walls?

RE: Dimensioning Hole depth on tubing

2 walls 6 places

RE: Dimensioning Hole depth on tubing

How come square tubing has 2 walls?

RE: Dimensioning Hole depth on tubing

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

RE: Dimensioning Hole depth on tubing

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

RE: Dimensioning Hole depth on tubing

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

This is why the section view is the right way.

RE: Dimensioning Hole depth on tubing

(OP)
If it is "Thru both walls/sides", would this not simply become just "thru"?

After 2 college degrees, a drafting certification and 10 years in the business, I have never seen or heard the use of "thru one wall" or the like..... guess thats why I like this forum so much.

In the instance that prompted this question, it is actually a small hole on one side and a large hole on the other, both concentric with each other. So for production simplicity, I want our shop to locate & drill the small hole thru first, then just come back and drill out a larger hole "thru one wall" ;) Otherwise they may end up locating and drilling both holes "thru one wall" which will take more time than needed.

The drawings for our in-house shop/factory are a quasi-drawing/work instruction all rolled into one..... fun, right?

Thanks,

VS
