Break Sharp Edges note
Break Sharp Edges note
(OP)
I'm trying to see if anyone can interpret what a note I have on a vendor drawing actually means.
"BREAK ALL SHARP (90% OR SMALLER) EDGES OF ALL SHEET METAL."
I've never seen the note stated that way before. Any idea what it is requesting?

As you can see, one side of it contains burr - feature that appears as sharp, "less than 90 deg." in absence of better word, edge.
Removing said edge seems the only interpretation I can come up with.
The percent sign could be result of using non-compatible font or something.
But I am open to suggestions.

I cannot make sense of your note. There ought to be a standard note on your fabrication drawings to break all burrs and sharp edges. On my drawings, I call up a maximum corner radius of 0.5mm. If you want anything more complicated than that, you need to show it in a view.

I can't make sense of it either! It's not my note!
KENAT,
I have an e-mail out to the vendor for a couple of days now...I think they are avoiding me.
I was thinking that it may just be someone not knowing how to use a ° symbol while typing...but want to be sure. Glad to see that I'm not the only one to have a bit of confusion with this note.

"I'm not exactly sure what this means as well, I would just call this out as 'break all sharp edges'."
ARE YOU KIDDING ME! This is his drawing...his signature is on it as the engineer!
Thanks for your help guys...

I agree with your comment about razor sharp edges on body panels. I have been to the hospital twice to get my hand stitched up from gashes caused by sharp edges on auto body sheet metal.

Honest - I had one of these lying weasels contest that the ball bearings in their assembly weren't sealed. I point out the regularly shaped blobs of grease that are going at exactly half the shaft rate as I turn the shaft and he tries to tell me that its grease build up on the shield. They also claimed an item was passivated - an item that looked like a wooly caterpillar after 2 hours in the salt fog chamber (passing was 24 hours and no specks.) The final straw was when a gear fell off the end of a sensor. They first claimed mishandling then, with the second one, stated we had not specified an axial retention requirement. Sigh.
Few sales guys are like this, but any that claim a razor edge has been deburred? Start with him and move towards upper management.
