I'll give it a try :-

1) The standard Cartesian coordinate system defines that

The 'A' axis rotates around the X axis.
The 'B' axis rotates around the Y axis.
The 'C' axis rotates around the Z axis.
So :-
The radio buttons Enable A or B axis is used to
define
the orientation of the rotary table i.e. is it
Parallel to the
X or Y Axis.

For our purposes we will assume 'A' is enabled which gives a
coordinate set of AXZ, where A is rotary, normally measured in
degrees.

2) Rotary Axis 'Y' value, normal default is 0.0.
This defines the Y position at which the Rotary table is mounted on
the bed of the machine. .e.g. If the table is mounted at Y 150 then
the contents of this item would be 150. This value is only used in the
positioning of the tool prior to Rotary work.
Depending on the particular post, the tool would normally move at
'Clearance Plane' height to this value prior to the commencement of
a Rotary exercise e.g. G00Y150Z50.

3) Radius Value
Linear 'Y' values are converted to Rotary values using the trig
equation 'Circumference = pi * Diameter'. One degree of movement
being Circumference / 360.
To be able to convert Linear values to Rotary Values we must define
the Diameter / Radius of the stock bars we wish to machine.
Therefore if we are machining 50mm diameter bars then the rad
value entered here would be 25mm.

Hi Michael,

I finally had a chance to go thru the video. Thanks. It does help a lot,
but it still doesn't explain what the parameters in the 4th axis popup box
are. I just need some real world explanations of what exactly those values
are and how to use them.

For example:

What data am I supposed to put in Rotary axis "X" or "Y"???
What exactly is a Radius value? Is that the radius of a finished part or
unfinished part? Perhaps the bottom of the slot after cutting?

The help files/manual are not very helpful in regards to explaining what to
enter in these boxes???

It would be helpful to see some photos of a part. Mabe even a video of a
machine making a cut.

Like for example, the slot example in the videos. You made a slot that was
80mm x 20mm, yet you entered 100mm in the radius value. Why? How does that
compute?

I'm still really confused on this.

Wade
