Under a certain plate thickness and cutting speed, there is an optimal laser power range, and the roughness of the cutting surface of the laser cutting machine is the smallest in this range. The deviation from the optimal power range will increase the roughness; further increasing or decreasing the power will cause over-burning or dross defects.
The figure below shows the relationship between the laser power and the quality of the cutting surface of the laser cutting machine at a cutting speed of 500 mm / s for a 2 mm thick low carbon steel plate. The method of measuring the roughness at the lower edge is used. The laser power can be divided into three areas: slag-hanging area, defect-free area and over-burning area.
Effect of laser power on cutting surface roughness
1) If the laser power of the laser cutting machine is too large, the melting range of the heat input over the ambassador's workpiece is larger than the range that can be driven out by the high-pressure airflow, and the molten metal cannot be completely blown off by the airflow, resulting in overburning.
2) If the laser power is too small and the heat is insufficient, the temperature of the molten product nearer to the lower edge is lower, and the viscosity is higher, so it cannot be completely blown off by the high-pressure air flow and stays on the lower edge of the cutting surface to generate dross. In severe cases, it cannot even be cut to form a cut.
3) In the non-defective area, there is an optimal laser power range (about 800-1000W), where the roughness of the cutting surface of the laser cutting machine is the smallest.
