Analysis of Fiber Laser Micro-drilling on Quartz
In the present research work, an analysis of fiber laser percussion micro-drilling of quartz is conducted in order to find out the effect of the process parameters on the entry diameter of micro-hole. A response surface methodology-based experimental design planned and experiments have been conducted for the analysis. The considered process parameters are laser power, pulse frequency, duty cycle, and air pressure. The experimental results reveal that a target value of the micro-hole diameter of 100 µm is generated with the combinations of pulse frequency of 52.05 kHz, duty cycle of 69.47%, laser power of 34.25 W, and air pressure of 1.50 kgf/cm2.
