The following provides an explanation of the most important
parameters for swiveling:
Before swiveling the axes you can move the tool to a safe retraction
position. The retraction methods available to you are defined in the
"Retraction position" parameter during set-up of the swivel data set.
The retraction mode is modal. On a tool change or after a block
search, the retraction mode last set is used.
Please refer to the machine manufacturer's instructions.
Warning
You must select a retraction position that precludes collision between
the tool and workpiece during swiveling.
Select whether to rotate the coordinate system, for example, to
execute a further swivel in the new coordinate system or whether to
really traverse the swivel axes. If you want to perform a machining
operation in the swiveled plane, you will need to be able to move the
swivel axes.
The coordinate system can be swiveled either axially or via solid or
projection angles. The machine manufacturer determines when
setting up the "Swivel" function which swivel methods are available.
Please refer to the machine manufacturer's instructions.
•
In the case of axial swiveling, the coordinate system is rotated
about each axis in turn, with each rotation starting from the
previous rotation. The axis sequence can be selected freely.
•
With the swiveling variant based on solid angles, the coordinate
system is rotated first about the Z axis and then in negative
direction about the Y axis. The second rotation starts from the
first.
•
When swiveling via projection angle, rotation is carried out about
two axes simultaneously, i.e. you can view two angles at the
same time. The third rotation is based on the first two.
You can select any of the axes.
This method is used, for example, for oblique drilling with angles
dimensioned in the side elevations of the part drawing. The side
elevations then correspond to the unrotated coordinate system.
The positive direction of each rotation for the different swivel methods
is shown in the help displays.
