LASER CUTTING METHOD OPTIMIZED IN TERMS OF MASS DEFECT PER UNIT LENGTH

摘要

The invention relates to an optimized laser cutting method for cutting a part (1) from a material by means of a cutting system (10) comprising: a laser source (11) for producing a laser beam (111) having a certain power; and a cutting head (12) comprising an end nozzle (13) for the passage of the cutting laser beam (111), said method being characterized in that it comprises a step of determining the cutting power Pd such that: Pd = Max(Popt; λe) where Max is the mathematical operator of the maximum, Popt is an optimal power of the laser beam (111) of the cutting system (10), which is predetermined in accordance with the part (1) to be cut, and/or with cutting parameters and/or with system (10) parameters, to minimize the mass defect per unit length of the part when the part (1) is being cut, λ is a leading coefficient representing the number of kW required for cutting the part per mm of the thickness of the part (1), and e is the thickness of the part in mm.
