The laser cutting technique of steel sheet with little scrap

Material utilization ratio can be improved e normously with great productivity, and cutting time is reduced largely by using the laser cutting technique of steel sheet with little scrap. Optimization of la ser cutting route and arrangement of parts with little scrap in a steel sheet is key nodus in the technique put forwards in the article. The principle of the ar rangement of laser cutting route is studied in the article. Furthermore, techniq ue of the programming practice is studied based on laser cutting technology of s teel sheet with little scrap. Finally, Combined with the practice of the laser c utting steel sheet of spin machine the technique of parts arrangement with zero scrap is studied. In the cutting practice of triangle strengthen part, by using the technique of zero scrap and compounding of the same part, the material utili zation ratio is increased from 65. 12% to 94.97%, and the average cut length of each part is reduced from 662mm to 448mm.
