FUNCTION PARAXMODE
To activate the PARAXMODE function, you must always
define three axes.
If you combine the
PARAXMODE and PARAXCOMP
functions, the TNC deactivates the PARAXCOMP
function for an axis that was defined in both functions.
When you deactivate PARAXMODE, the PARAXCOMP
function becomes active again.
Use the PARAXMODE function to define the axes the TNC is to use
for machining. You program all traverse movements and contour
descriptions in the principal axes X, Y and Z, independent of your
machine.
Define the three axes in the
PARAXMODE function (e.g. FUNCTION
PARAXMODE X Y W), which the TNC is to use to execute the
programmed traverse movements.
Proceed as follows for the definition:
Show the soft-key row with special functions
Select the menu for defining various plain-language
functions
Select FUNCTION PARAX
Select FUNCTION PARAXMODE
Select FUNCTION PARAXMODE
Define the axes for machining

13 FUNCTION PARAXMODE X Y W
Move the principal axis and the parallel axis simultaneously
If the PARAXMODE function is active, the TNC uses the axes defined
in the function to execute the programmed traverse movements.
If the TNC is to traverse a parallel axis simultaneously with the
associated principal axis, you can identify the respective axis by
additionally entering the character "
&". The axis with the & character
then refers to the principal axis.
The syntax element " &" is only permitted in L blocks.
Additional positioning of a principal axis with the " &"
command is done in the REF system. If you have set
the position display to "actual value", this movement
will not be shown. If necessary, switch the position
display to "REF value".
