Machine axes

Machine axes are the axes physically existing on a machine.
The movements of axes can still be assigned by transformations (TRANSMIT, TRACYL, or
TRAORI) to the machine axes. If transformations are intended for the machine, different axis
names must be specified during the commissioning (machine manufacturer).
The machine axis names are only programmed in special circumstances (e.g. for reference
point or fixed point approach).
Axis identifier
The axis identifiers can be set in the machine data.
Standard identifiers:
X1, Y1, Z1, A1, B1, C1, U1, V1
There are also standard axis identifiers that can always be used:
AX1, AX2, ..., AX<n>
15.1.5

Channel axes

Channel axes are all axes, which traverse in a channel.
Axis identifier
X, Y, Z, A, B, C, U, V
15.1.6

Path axes

Path axes define the path and therefore the movement of the tool in space.
The programmed feed is active for this path. The axes involved in this path reach their
position at the same time. As a rule, these are the geometry axes.
However, default settings define, which axes are the path axes, and therefore determine the
velocity.
Path axes can be specified in the NC program with FGROUP.
For more information about FGROUP, see "Feedrate (G93, G94, G95, F, FGROUP, FL,
FGREF) [Page 109]".
