先进陶瓷具有优异的耐热性、耐磨性和耐腐蚀性，可用于许多需要这些性能的工业应用。然而，陶瓷的高硬度和脆性使得用传统制造方法加工它们变得困难且昂贵。在本文中，我们介绍了定性分析切割速度和辅助气体压力等参数对莫来石氧化铝板激光切割的影响的工作结果。实验使用与光纤和商用切割头耦合的 500 W 脉冲 Nd:YAG 激光器进行。使用惰性气体（Ar）作为辅助气体，通过同轴锥形喷嘴将其喷射到工件上。以5mm/s的最大切割速度切割厚度为4mm的莫来石-氧化铝板。获得的结果表明，连接到光纤的脉冲 Nd:YAG 激光器是一种可行且灵活的工具，可成功切割由金属制成的部件。
Advanced ceramics have excellent resistance to heat, wear, and corrosion and are used in many industrial applications were these properties are required. However, the high hardness and brittleness of ceramics make them difficult and expensive to machine by conventional manufacturing methods. In this article we present the results of the work carried out to analyze qualitatively the influence of some parameters such as the cutting speed and the assist gas pressure on the laser cutting of mullite-alumina plates. The experiments were performed with a 500 W pulsed Nd:YAG laser coupled to an optical fiber and a commercial cutting head. An inert gas (Ar) was used as assist gas, which was injected to the workpiece through a coaxial conical nozzle. Mullite-alumina plates having a thickness of 4 mm were cut at a maximum cutting speed of 5 mm/s. The results obtained demonstrate that the pulsed Nd:YAG laser connected to an optical fiber is a feasible and flexible tool for a successful cutting of components made of m...
