● Axis by axis
In the case of axis-by-axis swiveling, the coordinate system is rotated about each axis in
turn, with each rotation starting from the previous rotation. The axis sequence can be freely
selected.
● Solid angle
With the solid angle swiveling option, the tool is first rotated about the Z axis and then about
the Y axis. The second rotation starts from the first.
● Projection angle
When swiveling using the projection angle, the angle value of the swiveled surface is
projected onto the first two axes of the right-angle coordinate system. The user can freely
select the axis rotation sequence.
The 3rd rotation is based on the previous rotation. The active plane and the tool orientation
must be taken into consideration when the projection angle is used:
– For G17 projection angle XY, 3rd rotation around Z
– For G18 projection angle ZX, 3rd rotation around Y
– For G19 projection angle YZ, 3rd rotation around X
When projection angles around XY and YX are programmed, the new X-axis of the swiveled
coordinate system lies in the old ZX plane.
When projection angles around XZ and ZX are programmed, the new Z-axis of the swiveled
coordinate system lies in the old Y-Z plane.
When projection angles around YZ and ZY are programmed, the new Y-axis of the swiveled
coordinate system lies in the old X-Y plane.
● directly
For direct swiveling, the required positions of the rotary axes are specified. The HMI
calculates a suitable new coordinate system based on these values. The tool axis is aligned
in the Z direction. You can derive the resulting direction of the X and Y axis by traversing
the axes.
Note
Direction of rotation
The positive direction of each rotation for the different swivel versions is shown in the help
displays.
