Abstract：Laser cutting machine was an important special processing equipment in modern machining.The Y-axis beam was complex and difficult to manufacture.In order to avoid the defects such as porosity,shrinkage and loose,and insufficient pouring in the process of sand casting of beam structure,a two-side bottom pouring system was designed.The results show that the casting core is designed by the model-free casting technology,the casting riser process is optimized by Procast software simulation,and the casting process scheme of the beam of the laser cutting machine is finally determined.
