Are all non-linear interpolation schemes (like circular, helical, NURBS, etc) approximated with lines by all CNC controls? For example, a circle by means of several chords so that linear interpolation can be done internally to approximate the circle within some tolerance limits? Are NURBS curves also done like this - even in today's digital controls? Can anybody comment on this.
