“…Laser processing is a noncontacting and abrasionless technique, which eliminates cutting forces and metal fracture. It also reduces limitations in shape formation with minimal surface damage and maximum processing efficiency [8,9]. The use of lasers in material drilling is gaining wide acceptance, especially in the thin sheet metal industry, because of its low operational cost and the high precision conferred by certain inherent properties of laser beams [10].…”

This paper reports theoretical and experimental results of drilling titanium sheets with a thickness of 0.2 mm using a nanosecond-pulsed laser. To describe morphological changes and the temperature distribution during nanosecond laser drilling, a physical model was established using ANSYS parametric design language (APDL) with life and death technology of ANSYS software. The influences of laser parameters such as laser energy and pulse number on the dimensions (depth and diameter) of the drilled holes were investigated with optical microscope. The crater depth and diameter could be increased by increasing the number of laser pulses and laser energy with some defects. Compared with experimental results, numerical results show slight difference, which is in the acceptable range.

“…The hole entrance diameter and laser power were detected to have a direct relation. Hanon et al (Hanon et al, 2012) compared the experimental and simulation data of laser drillings of 5 and 10.5 mm thick alumina ceramics using a Nd:YAG laser of 600 W. They found that peak power and duty cycle can be used effectively to change the crater depth without formation of any defects. Yinzhou et al (Yinzhou et al, 2012) used a 2D axisymmetric FEM thermal model to predict the spatter statement and HAZ during LBPD of 4.4mm thick alumina ceramics using a CO2 laser.…”

In the present research, the simulation of the Nickel-base superalloy Inconel 718 fiber-laser drilling process with the thickness of 1mm is investigated through the Finite Element Method. In order to specify the appropriate Gaussian distribution of laser beam, the results of an experimental research on glass laser drilling were simulated using three types of Gaussian distribution. The DFLUX subroutine was used to implement the laser heat sources of the models using the Fortran language. After the appropriate Gaussian distribution was chosen, the model was validated with the experimental results of the Nickel-base superalloy Inconel 718 laser drilling process. The negligible error percentage among the experimental and simulation results demonstrates the high accuracy of this model. The experiments were performed based on the Response Surface Methodology (RSM) as a statistical design of experiment (DOE) approach to investigate the influence of process parameters on the responses, obtaining the mathematical regressions and predicting the new results. Four parameters i.e. laser pulse frequency (150 to 550 Hz), laser power (200 to 500 watts), laser focal plane position (-0.5 to +0.5 mm) and the duty cycle (30 to 70%) were considered to be the input variables in 5 levels and four external parameters i.e. the hole's entrance and exit diameters, hole taper angle and the weight of mass removed from the hole, were observed to be the process output responses of this central composite design. By performing the statistical analysis, the input and output parameters were found to have a direct relation with each other. By an increase in each of the input variables, the entrance and exit hole diameters, the hole taper angel, and the weight of mass removed from the hole increase. Finally, the results of the conducted simulations and statistical analyses having been used, the laser drilling process was optimized by means of the desire ability approach. Good agreement between the simulated and the optimization results revealed that the model would be appropriate for laser drilling process numerical simulation.

“…Bandyopadhyay et al [2] presented a 400-W Nd:YAG laser drilling mechanism for 4-and 8-mm-thick Ti-6Al-4V alloys for aerospace applications and analyzed the parameters influencing laser drilling; their experimental results revealed that pulse repetition frequency and laser energy were the most influential. Hanon et al [3] used ANSYS finite element analysis to simulate temperature distribution in laser alumina ceramic plates. They studied the effect of laser peak power and pulse duration on drilling.…”

This paper reports theoretical and experimental methods for drilling alumina ceramic substrates by using a nanosecond-pulsed ultraviolet laser. A physical model was established using ANSYS parameter design language finite element software. The influence of laser parameters, such as laser fluence, number of pulses and its duration, and frequency, on morphology-depth, diameter, taper, and temperature distribution-was investigated using three-dimensional confocal laser scanning microscopy. Simulation and experimental results reveal that higher laser fluence and number of pulses produces larger drilling depths and diameters. Laser fluence, pulse duration, frequency, and pulse number of 5.10 J/cm 2 , 1000 μs, 20 kHz, and >9, respectively, can successfully drill through the alumina ceramic substrate. Pulse duration between 3 and 8 ms yielded the smallest hole taper.
