Note
The TOROT statement ensures consistent programming with active orientable toolholders for
each kinematic type.
Just as in the situation for rotatable toolholders, PAROT can be used to activate a rotation of the
work table. This defines a frame which changes the position of the workpiece coordinate
system in such a way that no compensatory movement is performed on the machine. Language
command PAROT is not rejected if no toolholder with orientation capability is active.

Align Z axis of the WCS by rotating the frame parallel to the tool orientation
As TOFRAME
Align Y axis of the WCS by rotating the frame parallel to the tool orientation
Align X axis of the WCS by rotating the frame parallel to the tool orientation
Align Z axis of the WCS by rotating the frame parallel to the tool orientation
The rotation defined with TOROT is the same as that defined with TOFRAME.
As TOROT
Align Y axis of the WCS by rotating the frame parallel to the tool orientation
Align X axis of the WCS by rotating the frame parallel to the tool orientation
Deactivate orientation parallel to tool orientation
Rotate frame to align workpiece coordinate system on workpiece
Translations, scaling and mirroring in the active frame remain valid
The workpiece-specific frame rotation activated with PAROT is deactivated
with PAROTOF.
