Movement in an inclined plane
The new work plane will be perpendicular to the orientation of the tool.
The Z axis keeps the same orientation as the tool.
The orientation of the X, Y axes in the new work plane depends on the spindle type and on how
its rotary axes are oriented.
When setting the machine up, it must be set as the spindle's resting position, when the tool is parallel
to the Z axis of the machine.
Later, every time the spindle is rotated, the relative tool coordinates will also rotate.
On the two machines on the left, only the main rotary axis has rotated.
On the contrary, in the machine on the right, to achieve the same tool orientation, both the main and
secondary rotary axes have rotated.
If in the machine on the right, we wanted to orient the X', Y' axes like in the other two cases, we would
have to program the following:
G49 T XYZ S-90
Programming S-90 means rotating -90º around the new Z' corresponding to the new work plane and,
this way, compensate for the rotation of the main rotary axis.
