Abstract
Owing to the exceptional physical and mechanical properties, alumina ceramics are widely applied in industrial manufacturing, where laser technology is pivotal for achieving high-precision cutting. This study investigates the laser ablation of alumina ceramics using fiber lasers, complemented by simulation to optimize processing parameters. The laser has a maximum average power of 150 W with a fiber core diameter of 25 μm. By varying laser power, frequency, and scanning speed, at an average power of 90W and a frequency of 400 Hz, the ablation efficiency and surface quality are enhanced while minimizing heat-affected zone of 50 μm. Simulation results accurately predict temperature distribution and material removal, aligning well with experimental data, thus advancing the precise machining of hard ceramics.
