If the rotation direction of the rotation axis is the reverse of what is described in
the table above, set a negative value for parameter No.19723 or 19725.
If the direction with an angular displacement of 0 differs from what is described
in the table above, specify parameters No.19730 and 19731, assuming that the
angle of the rotation axis in relation to the direction described in the table above
as the reference angle.
19730 Reference angle of the rotation axis
in the tool radius compensation for 5-axis machining (first set)
19731 Reference angle of the rotation axis
in the tool radius compensation for 5-axis machining (second set)

Set the workpiece coordinates of the origin of the table coordinate system used
for the tool radius compensation for 5-axis machining. Specify the parameter for
the three axes specified for parameters No.19720 to 19722. The intersection of
two rotation axes is assumed to be the origin of the table coordinate system.
