Underwater Laser Micromachining

The disturbances of vapor bubble to a laser beam in the underwater laser machinig process importantly limits the material removal rate and cut quality obtained. In this study the ultrasound was used to energize and break up the bubble while the laser beam was performing a.

To cope with this challenge this paper presents the roles of water temperature on cut dimensions in the underwater laser micromachining of titanium alloy ti 6al 4v.

Underwater laser micromachining. The effects of laser power traverse speed and number of laser passes were also examined in this study where groove width and depth were measured and analyzed. Laser micromachining has been widely used for decades to fabricate the micro and submicro component structures. By using the ultrasonic assisted underwater laser micromachining technique the ultrasound can energize water to actively flush the cut debris push the molten material away from the cut surface and rapidly cool the workpiece during the laser ablation of silicon in water. However thermal and physical damages are crucial issues associated with the process. Underwater laser ablation has been developed as a damage free micro ablation technique. According to the findings of this study the ultrasonic assisted underwater laser micromachining technique could be an alternative micromachining process to gain a higher material removal rate and. In this paper a comparison of the conventional dry and underwater laser micromachining of silicon is presented. This issue is more essential for the laser micromachining process that a precise and small trench cut is highly needed. In this paper experiment on uw lbmm is reported using a q switched ndyag laser for fabricating microchannels on 304 stainless steel. So in order to minimize the thermal effects underwater laser beam micromachining uw lbmm came into existence.
