Axes and coordinate systems
The figure below shows an example of the nomenclature of the axes on a milling-profiling machine
with a tilted table.
Axis selection
Of the 9 possible axes that may exist, the CNC allows the manufacturer to select up to 7 of them.
Moreover, all the axes should be suitably defined as linear, rotary, etc. through the axis machine
parameters.
There is no limitation to the programming of the axes, and up to 7 axes may be interpolated at the
same time.
Example of milling
The machine has three normal axes: X, Y and Z, one normal linear U axis controlled by the PLC,
an analog spindle (S) and an electronic handwheel.
Setting of general parameters AXIS1 (P0) through AXIS8 (P7).
The CNC activates a machine parameter table for each axis (X, Y, Z, U) and another one for the
spindle (S).
axis parameter AXISTYPE (P0) must be set as follows.
spindle parameter SPDLTYPE (P0) must be set as follows:
Likewise, axis parameter DFORMAT (P1) and spindle parameter DOFORMAT (P1) must be properly
set to indicate their display formats.
AXIS1 (P0) = 1 X axis associated with feedback X1 and output O1.
AXIS2 (P1) = 2 Y axis associated with feedback X2 and output O2.
AXIS3 (P2) = 3 Z axis associated with feedback X3 and output O3.
AXIS4 (P3) = 4 U axis associated with feedback X4 and output O4.
AXIS5 (P4) = 10 Spindle (S) associated with feedback X5 (1-6) and output O5.
AXIS6 (P5) = 0
AXIS7 (P6) = 11 Handwheel associated with feedback input X6 (1-6).
AXIS8 (P7) = 0
X axis AXISTYPE (P0) = 0 Regular linear axis
Y axis AXISTYPE (P0) = 0 Regular linear axis
Z axis AXISTYPE (P0) = 0 Regular linear axis
U axis AXISTYPE (P0) = 5 Regular linear axis controlled by the PLC
Spindle SPDLTYPE (P0) = 0 ±10V spindle analog output.
