IMPROVING THE QUALITY OF LASER DRILLING BY ASSISTED PROCESS METHODS OF STATIC SOLUTION AND MIST BLOWING

The use of static solution-assisted laser drilling can effectively improve hole roundness, decrease taper angle, and reduce recast layer thickness and hole wall slag adhesion.However, the enormous energy of the laser will evaporate the solution to form a suspension droplet and reduce the quality and efficiency of laser drilling.To deal with this de
