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