Interpolation by Bezier curves and NURBS Strategies of Machining of Complex Surfaces In CNC Milling

The increase in the productivity on machine with digital control passes, amongst other things, by the improvement of the programming of this machine. The language on which this programming is currently based is the standard 6983 which defines the principles of the code G. This last forward certain disadvantages to the sights of the new strategies of machining and creates a rupture of the numeric control on the level of manufacture. New formats, format by Bezier curves and NURBS, are born currently with the purpose of palliating to the lacks of the code G and to integrate CAO-FAO-CN channel completely. Our work aims to forward these new strategies of machining based on the interpolation of Bezier curves and NURBS like their new formats NC. A program in Visual BASIC 6.0 Windows pennies was developed making it possible to trace the trajectories of Bezier curves and B Spline in continuation of used in a software of FAO.
