Laser assisted machining methods are most powerful technique in the precise material processing compared with the conventional methods. The aim of this study is to investigate of machinability of tungsten carbide using laser deep engraving technique and to constitute a mathematical model for surface roughness and engraving depth. Confirmation experiments were performed using mathematical models. The experimental results show that the Tungsten Carbide can be machined by a fiber laser marking machine. The results of confirmation experiments show that the calculated values from the model and measured values from the experiments at the same conditions for both surface roughness and engraving depth are very close.
