12.4 Programmable rotation (ROT, AROT, RPL)

12.4 Programmable rotation (ROT, AROT, RPL)
Function
ROT/AROT can be used to rotate the workpiece coordinate system around each of the three
geometry axes X, Y, Z or through an angle RPL in the selected working plane G17 to G19
(or around the perpendicular infeed axis). This allows inclined surfaces or multiple workpiece
faces to be machined in one setting.
Syntax
ROT X... Y... Z...
ROT RPL=...
AROT X... Y... Z...
AROT RPL=...
Note
Each frame operation is programmed in a separate NC block.
Significance
ROT:
RPL:
AROT:
X... Y... Z... :
350
Absolute rotation, with reference to the currently valid workpiece
zero set with G54 to G57, G505 to G599.
Rotation in the plane: Angle through which the coordinate system
is rotated (plane set with G17 to G19)
The sequence in which the rotation is to be performed can be
specified via the machine data. The default setting is RPY notation
(= Roll, Pitch, Yaw) with Z, Y, X.
Additive rotation in relation to the currently valid set or
programmed zero point
Rotation in space: Geometry axes around which the rotation is
performed
