4.1.3 Linear and Rotary Axes
Principle axes: Coordinates of the X, Y and Z axes refer to the
workpiece zero point. Any deviations from this rule will be indicated.
Note for negative X-coordinates:
■ Not permitted for contour definition.
■ Not permitted for turning cycles.
■ Contour regeneration is interrupted.
■ The direction of rotation of arcs (G2/G3, G12/G13) must
be adjusted manually.
■ The position for tooth and cutter-radius compensation
(G41/G42) must be adjusted manually.
C axis: Angle data are with respect to the zero point of the C axis.
(Precondition: The C axis has been configured as a principal axis.)
For C-axis contours and C-axis operations, the following applies:
■ Positions on the front/rear face are entered in Cartesian
coordinates (XK, YK), or polar coordinates (X, C).
■ Positions on the lateral surface are entered in polar coordinates
(Z, C). Instead of C, the ”linear value CY” is used (”unrolled”
reference diameter).
Secondary axes (auxiliary axes): In addition to the principle axes, the
CNC PILOT supports:
■ U: Linear axis in X direction
■ V: Linear axis in Y direction
■ W: Linear axis in Z direction
■ A: Rotary axis around X
■ B: Rotary axis around Y
■ C: Rotary axis around Z
The auxiliary axes are only programmed in the MACHINING section,
using the functions G0 to G3, G12, G13, G30, G62 and G701. Circular
interpolation is only possible in the principal axes.
Rotary axes (auxiliary axes) are programmed in the MACHINING
section, using G15.
■ The DIN editor respects only address letters of the
configured axes.
■ The behavior of the rotary axis C depends on whether it
is configured as principle or secondary. The ”C axis
functions” G100..G113 apply for the principle axis C.
