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
Circular pattern Selection option for the following patterns:
Pitch circle
•
(only for G code)
Full circle
•
Z0 (only for Z coordinate of the reference point Z
ShopMill)
X0 X coordinate of the reference point X (abs)
Y0 Y coordinate of the reference point Y (abs)
α0 Starting angle for first position.
Positive angle: Full circle is rotated counterclockwise.
Negative angle: Full circle is rotated in clockwise direction.
α1 Advance angle - (for pitch circle pattern only)
After the first hole has been drilled, all further positions are advanced by this angle.
Positive angle: Further positions are rotated counterclockwise.
Negative angle: Further positions are rotated clockwise.
