Traversing reference points in tilted axes
With tilted axes, you use the machine axis direction buttons to cross
over the reference points. The TNC interpolates the corresponding
axes. Be sure that the function for tilting the working plane is active in
the Manual Operation mode and that the actual angle of the tilted axis
was entered in the menu field.
Setting a preset in a tilted coordinate system
After you have positioned the rotary axes, set the preset in the same
manner as for a non-tilted system. The behavior of the TNC during
presetting depends on the settings of Machine Parameter 7500 in
your kinematics table:
 MP7500, bit 5=0
With an active tilted working plane, the TNC checks during
presetting in the X, Y and Z axes whether the current coordinates of
the rotary axes agree with the tilt angles that you defined (3-D ROT
menu). If the tilted working plane function is not active, the TNC
checks whether the rotary axes are at 0° (actual positions). If the
positions do not agree, the TNC will display an error message.
 MP7500, bit 5=1
The TNC does not check whether the current coordinates of the
rotary axes (actual positions) agree with the tilt angles that you
defined.
Danger of collision!
Always set a reference point in all three reference axes.
If your machine tool is not equipped with axis control, you
must enter the actual position of the rotary axis in the
menu for manual tilting: The actual positions of one or
several rotary axes must match the entry. Otherwise the
TNC will calculate an incorrect datum.
