The present investigation deals with laser milling process of yttria-stabilized zirconia (YSZ), by using a Q-switched 30 W Yb:YAG fiber laser. First, the influence of laser operational parameters, laser beam scan speed, the number of time, and the sample surface is worked (number of repetition) and the scanning strategy was investigated. This first step allowed to identify the most suitable processing window in terms of surface quality and machined depth.

The experimental results demonstrate that the laser treatment is suitable for YZS highlighting high repeatability, process accuracy, short machining time, and the possibility to easily control the process outputs.

Abstract

The present investigation deals with laser milling process of yttria-stabilized zirconia (YSZ), by using a Q-switched 30 W Yb:YAG fiber laser. First, the influence of laser operational parameters, laser beam scan speed, the number of time, and the sample surface is worked (number of repetition) and the scanning strategy was investigated. This first step allowed to identify the most suitable processing window in terms of surface quality and machined depth. Then, a systematic approach based on full factorial design of experiment was developed and successfully adopted to identify and explain the effect of each operational parameter on laser–material interaction and on the process outputs: roughness, machined depth, and material removal rate. The experimental results demonstrate that the laser treatment is suitable for YZS highlighting high repeatability, process accuracy, short machining time, and the possibility to easily control the process outputs.
