Abstract

For mild steel of 5...25 mm thick, the parameters area of the maximum cutting quality has been determined experimentally. The conditions of cutting with minimum roughness are presented as a dependence of dimensionless values. It has been shown that the high-quality cutting features the specific volumetric input of laser energy, equal for any thickness. Normalized power W/λt(T_m-T₀), normalized velocity vb/γ (Peclet number) and kerf width have special optimum numbers.
