Simulation Research on Temperature Field of Laser Cutting of Fe-based Amorphous Magnetic Cores
In order to clarify the temperature field of laser cutting process of FeSiBCuNb amorphous nanocrystalline cores,the melt-solidification model,the multiphase flow model and the rotating body heat source whose radius is attenuated along the depth were used to simulate the three-dimensional temperature field of laser cutting in Fluent software with the life and death unit method.The influence of process parameters such as laser power and cutting speed on the cutting seam width and the thickness of thermal affected zone was studied.The results show that when the magnetic core is cut completely in thickness direction,the cutting seam width and the thickness of thermal affected zone show the morphology of narrow in upper,lower ends,and wide in middle part.With the increase of laser power or the decrease of cutting speed,the cutting seam width increases overall,and the cutting seam width in the thickness direction is more uneven.
