Programming a circle with known center point

To program a circle or arc with a known center point, use the "Circle center point" function.
The tool traverses a circular path from its actual position to the programmed target position
at the machining feedrate. The system calculates the radius of the circle/arc on the basis of
the entered interpolation parameter settings I and K.
