What factors will affect the accuracy of laser cutting for ST37 mild steel plate

There are several important factors that affect the accuracy of laser cutting for ST37 mild steel plate:

1. The size of laser spot after focusing: the smaller the laser spot after focusing, the higher the machining accuracy of laser cutting for ST37 mild steel plate.

2. The displacement precision of the worktable determines the repetition precision of laser cutting for ST37 mild steel plate. The higher the precision of the worktable, the higher the precision of ST37 mild steel plate cutting.

3. The greater the thickness of the workpiece, the lower the precision and the larger the slit. Because the laser beam is tapered and the slit is tapered, the slit of ST37 mild steel plate with thickness of 0.3mm is much smaller than that with thickness of 2mm.

4. The material of workpiece has certain influence on laser cutting precision. In the same case, the cutting accuracy of different materials of plasma cutting machine is slightly different, even for the same material such as ST37 mild steel plate, if the composition of materials is different, the cutting accuracy will also be different.
