A review of the key technologies for complex sculptured surface CNC cutting

Numerically controlled cutting is the high quality and high efficiency cutting approach for complex sculptured surfaces. Gouging - free and collision avoidance tool - path generation is the key technology for NC cutting. This paper attempts to review the key technologies of NC cutting for sculptured surfaces and the current deficiencies of conventional CAM systems for high speed cutting. Finally, the developing trends of the key techniques are discussed.
