Approach to high speed gas cutting process has been tried by some researchers from different points of view. In spite of many efforts of those researchers, only a few processes have been developed. To apply this process to NC cutting, the authors performed basic research to a great extent and recently successful results have been obtained. Good cutting surface has been obtained by the high speed cutting when a supersonic curtain-divergent nozzle is kept vertically to the cutting plane with high pressure oxygen at 5-17 kg/cm. Maximum cutting speed is over 4,000 mm/min and is over two times as fast as conventional processes. The authors describe the results of their basic studies on this method, and it's outline, although some part of this series of study is still under investigation.
