Parameters - "Pitch circle" position pattern
Parameter Description
LAB Repeat jump label for position
(only for G code)
PL Machining plane
(only for G code)
Axes Selection of the participating axes:
● XY (1st and 2nd axis of the plane)
(only for G code)
● ZC (rotary axis and assigned linear axis)
Note:
Rotary axes are only displayed in the selection field if they have been released for use
in the position pattern.
Please observe the information provided by your machine manufacturer.
Axes XY (at right angles)
X0 X coordinate of the reference point (abs)
Y0 Y coordinate of the reference point (abs)
α0 Starting angle for first position referred to the X axis.
Positive angle: Circle is rotated counter-clockwise.
Negative angle: Circle is rotated clockwise.
α1 Incrementing angle
R Radius
N Number of positions
Positioning
● Straight line: Next position is approached linearly in rapid traverse.
(only for G code)
● Circular: Next position is approached along a circular path at the feedrate defined in
the machine data.
Axes ZC (with G19)
Z0 Z coordinate of the reference point (abs)
C0 Start angle of the C axis (abs)
N Number of positions
(only for G code)
