10.1 Drilling
Parameter Description
Face Y:
center/ Position circle center on the face surface
off-center Position circle off-center on the face surface
Z0 Z coordinate of the reference point (abs)
CP Positioning angle for machining area
The CP angle does not have any effect on the machining position in relation to the work‐
piece. It is only used to position the workpiece with the rotary axis C in such a way that
machining is possible on the machine.
X0 or L0 X coordinate of the reference point (abs) or reference point length, polar
– (only for off-center)
Y coordinate of the reference point (abs) or
Y0 or C0
reference point angle, polar – (only for off-center)
Starting angle for first position referred to the X axis.
α0
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.

Peripheral surface C:
X0 Cylinder diameter ∅ (abs)
Z0 Z coordinate of the reference point (abs)
α0 Starting angle for first position referred to the Y axis.
Positive angle: Circle is rotated counter-clockwise.
Negative angle: Circle is rotated clockwise.
