HEATING MECHANISM IN RELATION TO THE LASER MACHINING PROCESS

Laser workpiece interaction mechanism is an important phenomenon which will assist in the development of laser machining systems. The intera ction mechanism is generally complicated and depends on the laser and workpiece properties. In the present study a mathematical analysis for the laser material removal by evaporation and radial ejection of liqu id is carried out. In the analysis the time unsteady problem is solved and nucleation explosions are predicted.
