21. AXES CONTROL
B–63002EN/01
NC FUNCTION
248
For T series, even if the X axis is not vertical to the Z axis (for T series,
the Y axis not vertical to the Z axis), they are assumed to form a
orthogonal coordinate system, simplifying programming. The movement
of each axis is automatically controlled according to the slant angle.

For the ordinary angular axis control function of the T series, the X–axis
is always used as the angular axis, while the Z–axis is always used as the
perpendicular axis. (For the M series, the Y–axis is always used as the
angular axis, while the Z–axis is always used as the perpendicular axis.)
With arbitrary axis angular axis control, however, any axes can be
specified as the angular and perpendicular axes, by specifying parameters
accordingly.
This function sets an axis (B–axis) independent of the basic controlled
axes X

and allows drilling, boring, or other machining
along the B–axis, in parallel with the operations for the basic controlled
axes. The X

and Z

axes can be used in two–path control mode.
