Switching geometry axes

Which channel axes are assigned to the geometry axis of the channel can be specified with the
As shown in the figure below, you can use axis Z1 as the third geometry axis named axis Z, which, together with axes X1
and Y1, form a geometry coordinate system used for interpolatory compensation. Alternatively, you can use axis Z2 as the
third geometry axis named axis Z, which also, together with axes X1 and Y1, form a geometry coordinate system used for
interpolatory compensation. In this way, axes Z1 and Z2 can be alternatively used as geometry axis Z in a part program.
Machine data for switching geometry axes
The workpiece geometry is described by a coordinate system that is formed by the geometry axes. A channel axis is
assigned to each geometry axis and a machine axis is assigned to each channel axis.
The required assignment for switching geometry axes is as follows:
MD10000 AXCONF_MACHAX_NAME_TAB
MD20050 AXCONF_GEOAX_ASSIGN_TAB
MD20060 AXCONF_GEOAX_NAME_TAB
MD20070 AXCONF_MACHAX_USED
MD20080 AXCONF_CHANAX_NAME_TAB
Format
The command is formatted as follows:
GEOAX
GEOAX(n, channel axis name)
GEOAX()
n = 1 to 3: number of the geometry axis to which a channel axis is assigned
Channel axis name: name of the channel axis that is assigned to a geometry axis
