Hi,
I’m fairly sure that on a CNC machine the z-axis is the axis parallel to the
spindle.
On a CNC surface grinder, the Z axis is what you would expect to be the Y axis.
But in reality you can name them however you like.

It is pretty easy to see WHY the z-axis is set up the way it is on a lath and a
mill and why it is different. You need a well defined “zero”. On a mill, the
machine's “zero" is the table and one a mill it is the chuck. A lathe has not

Shouldn't cross slide motion be X and carriage motion be Z on a lathe? Like a
mill tipped on its back.
On a mill, towards the tool on the spindle axis (Z) is + and table movement
(X) to the right is +
So think of standing on the left side of a Bridgeport then tipping it over to
the left.

Same here every machine I have used (12 years CNC machining). negative z
is always towards the chuck.
Or on a mill brings the tool down to table. Or table up towards tool

John,
Leaving aside right or left hand rules etc, leaning your head towards
your left shoulder shows that the relationship between the spindle and
the carriage is the same as on a vertical mill.
To bring the spindle closer to the carriage is a move in the -Z
direction.
If the argument is
There's been an interesting discussion on the Unimat users list about axis
direction. As usual someone can always find something on the web that supports
their opinion.
For example this one:

Everything is happy, the PID loops all behave the way they should. However,
one of the axes needs it's direction reversed.
