Features of automatic fiber laser cutting Compared with other thermal cutting methods, laser cutting has the general characteristics of fast cutting speed and high quality. Specifically summarized as the following aspects. (1) Good cutting quality Due to the small laser spot, high energy density and fast cutting speed, laser cutting can obtain better cutting quality. ①The laser cutting incision is narrow, the two sides of the incision seam are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm. ②The cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Even laser cutting can be used as the last process without mechanical processing, and the parts can be used directly. ③After the material is laser cut, the width of the heat-affected zone is very small, and the performance of the material near the slit is almost unaffected, and the workpiece deformation is small, the cutting accuracy is high, the geometric shape of the slit is good, and the cross-sectional shape of the slit is relatively regular. Rectangle. The comparison of laser cutting, oxyacetylene cutting and plasma cutting methods is shown in Table 1. The cutting material is a 6.2mm thick mild steel plate. (2) High cutting efficiency Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple numerical control worktables, and the entire cutting process can be fully numerically controlled. During operation, you only need to change the CNC program to cut parts of different shapes, which can be used for two-dimensional cutting and three-dimensional cutting. (3) The cutting speed is fast, and the laser with a power of 1200W can be used to cut 2mm thick low-carbon steel plates. , The cutting speed can reach 600cm/min. Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-cutting 5mm thick polypropylene resin board, and the cutting speed can reach 1200cm/min.
The automatic fiber laser cutting material does not need to be clamped during laser cutting, which can save tooling and fixtures, and save the auxiliary time of loading and unloading. (4) Non-contact cutting laser cutting There is no contact between the torch and the workpiece, and there is no tool wear. To process parts of different shapes, there is no need to change the 'toolThe laser cutting process has low noise, low vibration and no pollution. (5) The types of cutting materials are multi-metal, metal-based and non-metal-based composite materials, leather, wood, and fiber. But for different materials, due to their own thermophysical properties and different absorption rates for lasers, they show different laser cutting adaptability. Using C02 laser, laser cutting performance of various materials. (6) Disadvantages Clear light cutting. Due to the limitation of laser power and equipment volume, laser cutting can only cut medium and small thickness plates and tubes, and as the thickness of the workpiece increases, the cutting speed is significantly reduced. The cost of laser cutting equipment is high and the one-time investment is large.
