X, Y, Z On A Lathe

There is several standards that cover this topic, asme and an ISO one from what I remember. Tim

Almost proves the old saying that there are as many realities as there are persons on the planet.
Tony knows of at least 7 axises so maybe we should name one the T axis after him.

Dave, are you one of the guys that solved the enigma?
Time for my nap, Mike

Nope, but Alan Turing worked where I work now... ;)
And Donald Davies (packet switching, you know, how the internet works)
And Sir Robert Watson-Watt (RADAR)

I'm just a humble engineer though, not a high-browed scientist :(

Edit: Forgot Louis Essen, atomic clock maker, should remember him, it's what I'm messing with!

When working on Fadals, the CNC axes were as such:

X-to and away from the operator.
Y-right and left of the operator.
Z-up and down of the spindle.

We have a 20 X 40 two and a half axis Fadal mill, it also has a 4th axis that simply moves the coolant nozzle in a relationship with the tool in use IF you enable it and IF you are willing to program it, I believe that Fadal calls this feature "Servo Coolant".

Yikes, are your posts radioactive?

Good thing you didn't remember them all, they would just get in the way.

A two and a half axis mill that has 4 axises and a programmable coolant nozzle, boy you really know how to wreck a thread.

Other kind of atomic! They use a Caesium vapour and pump it with the atoms' ionisation energy/frequency, which is re-emitted when it returns to neutral - it's incredibly stable and a single frequency which is then counted down to once-a-second.
The Best Clocks in use are accurate to about a second in 158 million years, the next generation are getting difficult to measure, as they're in the one second in the lifetime-of-the-universe bracket...
I just distribute the time from 'em, accurate to a ten-millionth of a second everywhere it reaches, the easy bit.

My original objective was to identify and adopt conventional terminology when making notes about my machining exercises on a lathe. I keep a log book of the stuff done, what worked, what didn't, and why (when possible). Helps me digest and learn from it. Just thought that referring to the x,y, or z axis would be a new level of sophistication for me :)
Thanks everybody for the input.

I think life was wonderful as a machinist before all this XYZ crap was invented; I'm talking the early 1960s, when we had longnitudinal, cross feed, and little else; on mills, we had table feed, infeed and vertical feed; call me an old fart; guilty!
 
Oh Dear, Just to confuse things even more perhaps.
Being one who messed about in boats I referred to the "Y" axis on my mill as the "Port n Starboard" the "X" as "Fore n Aft". The "Z" was just "Up n Down". Still do at times. :confused:
It depends on what terms you are used to I guess. But, when talking to other swarf nuts it is best to learn the conventions and I am still trying. :chagrin:

ps. Just had a look at the Turning&LatheBasics.PDF now me ed aches. :faint:
