Circle Position Pattern (Holes2) - Siemens SINUMERIK 840D sl Operating Manual

8.1.12

Circle position pattern (HOLES2)

Function
You can program holes on a full circle or pitch circle with defined radius with the "Circle
position pattern" cycle. The basic angle of rotation (α0) for the 1st position is relative to the X
axis. The control calculates the angle of the next hole position as a function of the total
number of holes. The angle it calculates is identical for all positions.
The tool can approach the next position along a linear or circular path.
Procedure
Parameter Description
LAB Repeat jump label for position
(only for G code)
PL Machining plane
(only for G code)
Circular pattern Selection option for the following patterns:
Pitch circle

Full circle

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 counterclockwise.
Negative angle: Circle is rotated clockwise.
α1 Advance angle - (for pitch circle only)
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
