Description

Technical Field

[0002] A plasma cutting machine is a type of cutting device. The plasma cutting machine utilizes plasma cutting technology to generate a high-temperature and high-pressure plasma through high-frequency arc discharge. These plasmas excite gas molecules into positively and negatively charged ions, thereby forming a plasma beam. After being accelerated by a nozzle, the plasma beam instantaneously heats the metal material on the surface of the workpiece to a high temperature, causing it to oxidize and melt rapidly. At the same time, the force of the plasma beam can also blow away the molten metal, thus forming a cut. Composite materials, especially carbon fiber composite materials, have a wide range of applications in the fields of aerospace, automotive, national defense, etc. due to their high specific strength, high specific modulus, high fatigue resistance, and strong fracture resistance. These fields have extremely high requirements for the accuracy of components, and traditional cutting methods are difficult to meet the needs.
