Laser Cutting Technology: An Analysis Of Core Principles, Advantages, And Application Areas
As a core process in modern manufacturing, laser cutting technology utilizes a high - energy - density laser beam to achieve efficient material processing. Since the birth of the laser in 1960, this technology has continuously evolved and become the preferred solution for processing both metallic and non - metallic materials. The following comprehensively analyzes laser cutting technology from aspects such as technical principles, core advantages, applicable materials, application scenarios, and future trends.
Core Principle: The Synergistic Effect of Thermal Effect and Gas Flow
In laser cutting, a high - power laser beam is generated by a laser generator and then focused by a focusing lens into an extremely small spot (usually with a diameter of 0.1 - 0.3 mm), generating an energy density as high as 10⁶ - 10⁸ W/cm². When the beam acts on the material surface, the instantaneous heating causes the material to rapidly melt, vaporize, or burn. Meanwhile, high - pressure gas (such as oxygen or nitrogen) coaxial with the beam blows away the molten material, forming a smooth cutting seam. This process can be divided into four modes according to the material properties:
1. Vaporization Cutting: Used for non - metallic materials such as wood and plastic.
2. Melting Cutting: Suit...
