Abstract In this paper, Pythagorean hodograph (P-H)

curve theory is used for high-speed contouring applications.

There are large contouring errors around sharp corners

when low-bandwidth servo controllers ...

Various methods for parametric interpolation of NURBS

curves have been proposed in the past. However, the errors

caused by the approximate nature of the NURBS interpolator

were rarely taken into account. ...
