✦ Synopsis

In describing the tool path for a certain CNC machine, it is often required to approximate Bezier curves by arc splines with the number of arc segments as small as possible. We give a new method for approximating quadratic BCzier curves by G' arc splines with smaller number of arc segments than the biarc method. Numerical results are given to illustrate the efficiency of the algorithm for the previously used examples of quadratic Bezier curves.

Sections of parametric surfaces defined by equally spaced parameter values can be very unevenly spaced physically. This can cause practical problems when the surface is to be drawn or machined automatically. This paper describes a method for imposing a good parametrization on a curve constructed by
