The traditional sheet metal process for laser cutting of metal sheets involves the following steps: shearing punching bending welding process or flame plasma cutting bending welding process. In the face of orders with multiple varieties, small batches, customization, high quality, and short delivery times, it shows obvious unsuitability. Laser cutting technology as a; Cut and Punch "; The emergence of alternative processes.

It has the characteristics of flexibility and high flexibility, so it is often used in the manufacturing of irregular (or complex shaped) workpieces and samples (single piece or extremely small batch), gradually replacing some traditional Sheet Metal Processing techniques. Traditional sheet metal cutting equipment holds a considerable market share in the market, although they also have their own unique advantages.

But compared to modern processes such as laser cutting, the disadvantages are very obvious, greatly affecting the competitiveness of enterprises. CNC cutting machines are mainly used for straight cutting and can only be used for cutting sheet metal in straight lines; (CNC/turret) Punching machines have limitations on cutting steel plates with a thickness of 1.5mm or more, and the surface quality is poor, with high costs and noise, which is not conducive to environmental protection.

Flame cutting, as a traditional cutting method, is only suitable for rough machining when cutting through thermal deformation, cutting width, waste materials, and slow processing speed; Plasma cutting and precision plasma cutting are similar to flame cutting. When cutting thin steel plates, the thermal deformation is too large and the slope is also large. They are powerless when precision is required, and the consumables are relatively expensive.
