The metal laser assisted cutting principle of laser cutting machine

by：Transon 2020-10-28

Metal laser cutting machine laser aided cutting is based on high temperature hot cutting, the strength of the metal decreases with the rise of temperature, and the elongation increases, it is well known fact. Heating is the purpose of cutting temperature heating softening hard hard cutting material, with a tool for cutting, so as to reduce the cutting force and the deformation caused by cutting force. Flutter, change the cutting shape, make it more straight, lower surface roughness and to a certain extent, improve the life of cutter. Existing of cutting of high temperature electric heating method. Oxyacetylene flame and plasma heating, etc. Provides a new method for laser irradiation. The laser beam reflected mirror M1 is direction along the slip board, by the slide carriage of mirror M2 to rest on the reflector on the M3 and M4, then through the lens L focus on the front of the main cutting edge tool, with heating cutting shear deformation zone. In cutting difficult-to-machine Inconel718 nickel base alloy, cutting force is proportional to the relationship with the laser power, laser assisted cutting can significantly reduce the cutting force. As for the change of the cutting tool life after laser-assisted, associated with high temperature resistance of cutting tool materials, ceramic blade increases, the life of a cemented carbide blade life. Compared with other heating methods, laser power and its spatial distribution is easy to control, can focus on heating shear deformation zone, and not too much heat and cutter contact chip, this is to reduce the cutting force and prolongs the service life of cutting tools is beneficial
