What does RKO mean on a drawing?

What does RKO mean on a drawing?

What does RKO mean on a drawing?

(OP)
What does RKO mean on a drawing?  I saw it on a drawing in refrence to a hole.  Can someone explain what it means?  Thanks

RE: What does RKO mean on a drawing?

"KO" could mean "knock-out"; not sure about "R".

Is part in question sheet metal?

RE: What does RKO mean on a drawing?

(OP)
It's in .06 AL

RE: What does RKO mean on a drawing?


The call-out is not standard.

"Round Knock-Out" would be my best guess.

RE: What does RKO mean on a drawing?

R = radius, perhaps?

Quote (KENAT):

What if any drawing standard, or country, or industry...?
Well, OP speaks English and measures material in Inches.

I suggest buying copy of Y14.38 - 2007 Abbreviations and Acronyms for Use on Drawings and Related Documents. If "RKO" is not there, then it is not standard in America.

Or we could start flame war about "industry standards" smile

RE: What does RKO mean on a drawing?

CH,
Good guess!

This is a beautiful example of why they want both to have standards and remove words from drawings. I bet you the guy who wrote it knew what he meant! :)

RE: What does RKO mean on a drawing?


Relativistic Klystron Oscillator would be my second guess.

RE: What does RKO mean on a drawing?

Back in the day it was common to see engineer's initials on drawing notes. Never understood it.

RE: What does RKO mean on a drawing?

CheckerHater, that was a bit unnecessary.  

Back in England I spoke English and used inches about 1/2 the time.  There were plenty of non standard terms and abbreviations there V here in the US.

Many component drawings done in other parts of the world that have to interface with components designed in imperial units/American customary will use inches.

Old drawings from many parts of the Commonwealth will be in inches.

Many industry sectors have their own common terms & abbreviations.

Giving/confirming any of this information might help lead to an answer.

dsjon10 sounds like you may need to go back to the drawing originator/whoever you got it from if possible.

RE: What does RKO mean on a drawing?

Kenat,

Sorry; didn't mean to get offensive.

Would you agree that if it's not in ASME or ISO "abbreviations", then it should be explained on the face of the drawing?

RE: What does RKO mean on a drawing?

Sure, that's why I asked about what standards/country.

However, from the point of view of answering the OP's question and helping him out is why I asked about industry etc.  While abbreviations not in a referenced standard (could be an industry or company standard) or defined on the drawing shouldn't really be used, in practice they sometimes are used - especially where they are common in a specific industry sector etc.

However, I'm guessing you knew that already.winky smile
