Abstract: In order to solve the problems of accurate and automatical identification of  information for flame cutting during the automatic programming process,  the representation and characteristics of auxiliary line for cutting and the contour line of part included in the layout drawing of parts were investigated and the characteristics of region in AutoCAD system was analyzed, a method to automaticly identify the information for flame cutting based on region was put forward.And then the identification process of this method was illustrated and effective methods to solve the potential problems that may appear during the identification process were proposed.At last, an experiment was done to evaluate this method. The experimental results show that this method is convenient and efficient and the identified information is accurate and complete. This method lays the foundation for getting automaticly and accurately NC cutting program.
