4.10 C-Axis Machining
4.10.1 General C-Axis Functions
Select C axis G119
If several C axes are available, use G119 to select a C axis and to
switch the active C axis during machining.
G119 assigns the C axis entered in ”Q” to the slide. Before assigning
an active C axis to another slide, cancel the previous assignment with
G119 without Q.
Parameters
Q:
Number of the C axis – default: 0
■ Q=0: Cancel the current assignment of C axis to slide.
■ Q>0: Assign the C axis to a slide.
Reference diameter G120
G120 determines the reference diameter of the unrolled lateral
surface. Program G120 if you use ”CY” for G110 to G113. G120 is a
modular function.
Parameters
X:
Diameter
Zero point displacement, C axis G152
G152 defines a zero offset for the C axis (reference: machine
parameter 1005, ff ”reference point C axis). The zero point is valid until
the end of the program.
Parameters
C:
Angle of the ”new” C-axis zero point
Standardize C axis G153
G153 resets a traverse angle >360° or <0° to the corresponding angle
modulo 360° – without moving the C axis.

hining
G153 is only used for lateral-surface
machining. An automatic modulo 360°
function is carried out on the end faces.
