CO₂ 레이저절단기를 이용한 자동차구조용 열간압연강의 절단특성에 관한 연구

In the cutting of plate steel, the quality of the cut surfaces is strongly dependent on the cutting conditions such as cutting speed, plate thickness, kerf width and gas pressure etc The cutting tests of plate steel were earned out using Laser cutting machine. The width and surface roughness of a section are examined at various cutting conditions. This paper deals with cutting characteristics of Steel Automobile Press Hot using CO₂ Laser Cutting Machine
