Arbitrary conic segments can be specified in the rational Bézier form, r(ξ ) for ξ ∈ [0, 1], by control points p 0 , p 1 , p 2 and a scalar weight w 1 . An expression for the cumulative arc length function s(ξ ), amenable to accurate and efficient evaluation, is required in formulating real-time CNC

Virtually any desired time variation V (t) of the feedrate along a curved path can be realized by real-time CNC interpolator algorithms for the Pythagorean-hodograph (PH) curves: the only stipulation is that V (t) should admit a closed-form indefinite integral F (t). Different feedrate variations V
