INFLUENCE OF PARAMETERS OF LASER CUTTING BURR SURFACE CUTTING OF STEEL PLATES
A mathematical model that adequately describes the effect of LC parameters on the surface roughness of the cut with no burrs is worked out, and the optimization mode LC using the methods of decision theory is given. It is shown that the surface roughness decreases with increasing speed and focal length decreases. Increasing the radiation power of the gas pressure and the thickness of the sheet has a negative impact on the roughness.The nomogram, allowing LC to assign modes for minimum roughness on sheets of different thickness steel St. 3 is received.
