Abstract: An automatic laser cutting technology with the processing ability of cold rolled sheet, hot rolled sheet and pickling sheet sample was developed. The automatic laser cutting process of the whole process of automatic loading, automatic marking, automatic generation of cutting model and cutting sample, automatic sorting and automatic finishing was realized. The technology was compared with the traditional processing technology, and the advantages of automatic laser cutting method for processing plate samples were studied. The research results could provide a theoretical basis for improving the processing efficiency and quality of plate samples in metallurgical industry.
