2.1.3 Channel axes
Meaning
Each geometry axis and each special axis is assigned to a channel. Geometry axes and
additional axes are always traversed in "their" channel.
2.1.4 Geometry axes
Meaning
The three geometry axes always make up a fictitious rectangular coordinate system.
By using FRAMES (offset, rotation, scaling, mirroring), it is possible to image geometry axes
of the workpiece coordinate system (WCS) on the BCS.
Application
Geometry axes are used to program the workpiece geometry (the contour).
Plane selection G17, G18 and G19 (DIN 66217) always refers to the three geometry axes.
That is why it is advantageous to name the three geometry axes X, Y and Z.
2.1.5 Replaceable geometry axes
Meaning
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.
