Value range with Euler angle
The angles are defined uniquely only within the following value ranges:
Rotation around 1st geometry axis: 0° ≤ X ≤ +180°
Rotation around 2nd geometry axis: -180° ≤ Y ≤ +180°
Rotation around 3rd geometry axis: -180° ≤ Z ≤ +180°
All possible rotations can be represented with this value range. Values outside the range are
normalized by the control into the above range. This value range applies to all frame
variables.
To ensure the angles written are read back unambiguously, it is absolutely essential to
observe the defined value ranges.
Note
If you want to define the order of the rotations individually, program the desired rotation
successively for each axis with
The working plane also rotates
The working plane defined with G17, G18 or G19 rotates with the spatial rotation.
Example: Working plane G17 X/Y, the workpiece coordinate system is positioned on the top
surface of the workpiece. Translation and rotation is used to move the coordinate system to
one of the side faces. Working plane G17 also rotates. This feature can be used to program
plane destination positions in X/Y coordinates and the infeed in the Z direction.
Condition:
The tool must be positioned perpendicular to the working plane. The positive direction of the
infeed axis points in the direction of the toolholder. Specifying
compensation in the rotated plane.
