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
Turning
