Parameter Description
LAB Repeat jump label for position
(only for G code)
PL Machining plane
(only for G code)
Position pattern Selection option for the following patterns:
Line

(only for G code)
Grid

Frame

Z0 (only for Z coordinate of the reference point Z
ShopMill)
X0 X coordinate of the reference point X (abs)
This position must be programmed absolutely in the 1st call.
Y0 Y coordinate of the reference point Y (abs)
This position must be programmed absolutely in the 1st call.
α0 Angle of rotation of the line referred to the X axis
Positive angle: Line is rotated counterclockwise.
Negative angle: Line is rotated clockwise.
L0 Distance of 1st position to reference point - (for line position pattern only)
L Distance between positions - (for line position pattern only)
N Number of positions - (for line position pattern only)
αX Shear angle X - (for grid or frame position pattern only)
αY Shear angle Y - (for grid or frame position pattern only)
L1 Distance between columns - (for grid or frame position pattern only)
L2 Distance between lines - (for grid or frame position pattern only)
N1 Number of columns - (for grid or frame position pattern only)
N2 Number of lines - (for grid or frame position pattern only)

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.
