Circle or pitch circle position pattern (HOLES2)

Function
You can program holes on a full circle or a pitch circle of a defined radius with the "Circle
position pattern" and "Pitch circle position pattern" functions. 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.
Rotary axes
If rotary axes are set up on your machine, you can select these axes for the "circle" or "pitch
circle" position patterns.
