Activation
Axis replacement is activated by the program command:
GEOAX([n, channel axis name]...)
n=0: Removes an axis from the geometry axis grouping
n=1, 2, 3: Index of the geometry axis
GEOAX( ): Establishes the basic setting defined via MD for the assignment of
channel axes to geometry axes
Channel axis name: Name of channel axis, which is to operate as a geometry axis
A channel axis, which has been designated a geometry axis, can only be addressed under
its geometry axis name. The geometry axes names themselves remain unchanged.
Geometry axes can be replaced either individually or as a group in one command.
Supplementary conditions
As a basic rule, any channel axis designated as a geometry axis can be replaced by another
channel axis.
In this case, the following restrictions apply:
• Rotary axes may not be programmed as geometry axes.
• A geometry axis, which has the same name as a channel axis, cannot be replaced by
another channel axis (alarm message). Nor can an axis of this type be removed from the
geometry axis grouping. It cannot change its position within the geometry axis grouping.
• Both axes in each of the axis pairs involved in the replacement operation must be block-
synchronized.
• The following functions may not be active when geometry axes are replaced:
– Transformation
– Spline interpolation
– Tool radius compensation
– Tool fine compensation
• Any active DRF offset or zero offset external will remain operative. They both act on
channel axes. The channel axis assignment is not affected by the replacement of
geometry axes.
Replacement of geometry axes
All frames, protection zones and working area limitations are deleted.
They may need to be reprogrammed after the replacement operation.
The system response to replacement of geometry axes is, therefore, identical to its response
to a change (switch on/off, switchover) in a kinematic transformation.
