can anyone explane all 8 axes?

[zander1]

Sorry did not know what forum to put this in.

I think I know the first 3 axes,
but can't think of what all 8 would be.
Can some one tell or show me please?

Zander,

That's what makes cnc so exciting, probing into those other dimensions in the universe

Actually, if you are thinking of an 8 axis motion controller, just think of it as being 8 different servo motors on some piece of automated packaging equipment. The 8 axis are not necessarily trying to drive a toolbit to a certain position, but may operate several different machine slides, etc.

This link will show most of them.

Lol, Benny you had me going there for a few seconds.... I was expecting to see an 8 axis machine

[Bloy2004]

me too!

LMAO Benny that's a 16 axis page !

[zander1]

sorry 8 axis

Benny, i think your humour is AXED!
LMAO!!!

but not half-axed

Are the 8 "axes" X, Y, Z (left-right, front-back, up-down), A, B, C (rotation around x-y-z respectively), and any two switch controls like motor on-of and coolant on-off?

robotic regards,

Zander, Though I did make a joke out of your post, I would like to know the real answer to your question too. When someone does post the right answer I will try and do a stick drawing of all the axis movements for a permanent reference.

I hope you also laughed at the joke, it wasn't meant to take the mickey out of you, but just be a bit of fun.

Benny, that was very funny!

I agree with Hu, 8 axis simply means that you can control 8 motors. It's totally up to the machine designer to decide what the motions are. Every machine is different.

For example, a hexapod might need 6 axis for the table.

Or take a straight forward 3 axis machine, add a rotary axis for a fourth. Add a C axis to the spindle, making it 5. Then you could add an additional Spindle for cutting two parts at once. This would make it 6. Add a rotary axis, and C rotation to the spindle and you get 8 axis needed.

We have a high volume chair rail machine at work. It will mortise and tenon both ends of a part, on all sorts of wierd angles. This machine has 8 motors to allow us to create programs that move everything into position. This is just for ease of setup. 4 direction on each end of the machine. Once its set up, the motors don't move anything, they just hold postion for the production run.

Anyways, I don't think that there is a hard and fast rule that says
AXIS 1 =X
AXIS 2 = Y
AXIS 3 = Z
AXIS 4 = C ROTATION OF (HORIZONTAL) SPINDLE
AXIS 5 = W TILT OF SPINDLE HEAD
AXIS 6 = ROTATY INDEXER
AXIS 7 = PART FLIPPER
AXIS 8 = BACK SCRATCHER

As far as I can tell, once you get past 3, every machine is unique.

Axis:
A straight line about which a body or geometric object rotates or may be conceived to rotate.

Mathematics.
An unlimited line, half-line, or line segment serving to orient a space or a geometric object, especially a line about which the object is symmetric.
A reference line from which distances or angles are measured in a coordinate system.
A center line to which parts of a structure or body may be referred.
An imaginary line to which elements of a work of art, such as a picture, are referred for measurement or symmetry.

Axis could easily be un limited do to the fact that any movement that derived from a point / axis from another known point / axis / line. Sorry if that does not make sense, but what I am trying to say is that a machine could have virtually any amount of axis's depending on the level of Automation you want to achive. In most cases, and with most machines we are all familuar with the X - Y - Z ! Left / Right, Forward / Back, Up / Down. As described above A, B, and C sometimes are Rotational.

Extend your arm (God was such a wonderful Engineer). You have numerious "Axis's" with the extension of your arm, thru your elbow, wrist etc. Now, entend your arm above your head, you now have many new "Axis's" because the Plane or Axis just changed, although from a fixed point, your shoulder!

Don't try to "over think" the concept of Axis. They are Fixed movements, nothing more! Good Luck! Hope I helped and not hindered this conversation.
