Compared with other thermal cutting methods, laser cutting has the overall characteristics of fast cutting speed and high quality. Specifically summarized as follows.

 

⑴ Good cutting quality

Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can achieve good cutting quality.

① The laser cutting incision is narrow, with both sides of the cutting seam parallel and perpendicular to the surface, and the dimensional accuracy of the cutting part can reach ± 0.05mm.

② The cutting surface is smooth and beautiful, with a surface roughness of only a few tens of micrometers. Even laser cutting can be used as the final process without mechanical processing, and the components can be directly used.

③ After laser cutting, the width of the heat affected zone of the material is very small, and the performance of the material near the cutting seam is almost unaffected. Moreover, the workpiece deformation is small, the cutting accuracy is high, the geometric shape of the cutting seam is good, and the cross-sectional shape of the cutting seam presents a relatively regular rectangular shape. The comparison of laser cutting, oxyacetylene cutting, and plasma cutting methods is shown in Table 1. The cutting material is 6.2mm thick low-carbon steel plate.

⑵ High cutting efficiency. Due to the transmission characteristics of laser, laser cutting machines are generally equipped with multiple CNC workstations, and the entire cutting process can be fully CNC controlled. When operating, simply changing the CNC program can be used to cut parts of different shapes, which can perform both two-dimensional and three-dimensional cutting.

⑶ Fast cutting speed

Using a laser with a power of 1200W to cut 2mm thick low-carbon steel plates, the cutting speed can reach 600cm/min; Cut 5mm thick polypropylene resin board with a cutting speed of up to 1200cm/min. The material does not need to be clamped and fixed during laser cutting, which not only saves tooling fixtures but also saves auxiliary time for loading and unloading.

(4) Non contact cutting

During laser cutting, there is no contact between the cutting torch and the workpiece, and there is no tool wear. Processing parts of different shapes does not require changing the "tool", only changing the output parameters of the laser. The laser cutting process has low noise, low vibration, and no pollution.

There are many types of cutting materials

Compared with oxyacetylene cutting and plasma cutting, there are many kinds of laser cutting materials, including metal, non-metal, metal matrix and non Metal matrix composite, leather, wood and fiber. However, for different materials, due to their own thermal physical properties and different laser absorption rates, they exhibit different laser cutting adaptability. Using CO2 laser, the laser cutting performance of various materials is shown in Table 2.

(6) Disadvantages: Due to limitations in laser power and equipment volume, laser cutting can only cut medium to small thickness plates and pipes. Moreover, as the thickness of the workpiece increases, the cutting speed significantly decreases.

Laser cutting equipment is expensive and requires a large one-time investment.
