Abstract:High speed machining technique, which features in high efficiency, high precision, high flexibility and high quality, can be applied not only to aluminum, cast iron and steel, but also to high hardness material, and it can be regarded as a new direction of modern manufacture technique. In NC machining, compared with the traditional linear interpolation, NURBS interpolation tool path has the particular characteristics of high speed, high precision and high surface quality, and it is the core fundamental technique with high speed machining techniques. High speed machining cell techniques are based on CNC controller and CAM software package. This paper explains the characteristic and technique points of NURBS interpolation through discussing and researching NURBS interpolation tool path generating method and key techniques of NURBS interpolator in CNC, etc. and points out that fiveaxis NURBS interpolation and the intelligent NURBS interpolation method, which features in controlling the feed speed of NURBS interpolation continuously and dynamically, are the direction of future researching.
Keywords:NURBS  high speed machining  CNC  CAM
