Please help! Chamfer show? 2

[kulagin]

How I must show chamfer along the contour?

 

[pmarc]

I would go with "all around" note below the chamfer dimension, however my opinion is not supported by any statement or figure in Y14.5.

"All edges on this face"?

When it's critical to leave sharp edges, or control an edge break in any way, I try and get specific, and have even created separate views, and second drawing sheets for those views, to show what I want as clearly as possible.

"All around" or "as shown" I think is safe.

Chris,

I'll have to disrespectfully disagree . I've had inspector-type persons tell me that "all around" can be ambiguous for a block like the OP shows, i.e. it can be interpreted as "all around the face indicated", "all around this edge", or "all around the whole part". Thus my advice is to be specific if you want certain edges treated differently. I think the OP's drawing shows what is required without any further comment, i.e. by depiction of the chamfer desired.

 

[kulagin]

Thanks for your advice! For clarity, see another example of a similar problem...

 

[kulagin]

Small correction. One face showed incorrect in last drawing.

I use a general note on drawings which states;
"All undimensioned chamfers 1x45"
That way we only have to show the geometry of the chamfer and not bother with a callout.

Ninja182,
The method you use is fine if all chamfers of a part are 1x45deg.

However if you imagine that OP has such remark on a print but for some reasons he needs to assign 2x45 chamfer on those specific edges, then he still has to figure out how to describe that those all around edges are different than the others.

 

[btrueblood]

"All chamfers 1x45" works when the planes all intersect at 90 degrees. When they don't...which face is the 45 measured from?

Kulagin, in your last post, I would click the little button buried somewhere in a menu in SolidWorks, something to the effect of "show tangent edges". Better, in my opinion, is to include the isometric view on your drawing, and even call out the radius on that view.

 

[kulagin]

Thanks again! In fact, I need to know how to show such elements professionally. I was hoping that someone has seen it in practice or in the standards. The drawing complex details in isometric view can not give understanding.

btrueblood, as I understand, you recommend to write "all around this edge"?

 

[btrueblood]

Sure, if it's shown on the isometric view. Or just the radius callout, as where it applies is pretty clear from the iso view.

 

[ctopher]

Either way, your machinists need to be trained how you do it. Not all know how to read drawings the same.

Just interesting, that this is not specified in the standards or manuals for engineering drawing, because such element is very common.

Arguably kulagin it's covered by 'show as many views as necessary' or whatever the wording is.
