2.1.5 Replaceable geometry axes
Significance
The "Replaceable geometry axes" function allows the geometry axes in a grouping to be
replaced by other channel axes.
Axes that are initially configured as synchronous special axes in a channel can replace any
selected geometry axis in response to a program command.
Example
On a machine with two Z axes, Z1 and Z2, either of the Z axes can be programmed as the
geometry axis in response to an instruction in the part program.
Activation
Axis replacement is activated by the program command:
GEOAX([n, channel axis name]...)
n=0:
n=1, 2, 3:
GEOAX( ):
Channel axis name:
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.
Basic logic functions: Axes, coordinate systems, frames (K2)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Removes an axis from the geometry axis grouping.
Index of the geometry axis
Establishes the basic setting defined via MD for the assignment of
channel axes to geometry axes.
Name of channel axis, which is to operate as a geometry axis.
