The model assumes that the fluence absorbed along the walls is distributed with a linear increase from the edge to the tip of the groove. The depth progress of the machined groove is recursively calculated based on the depth increments induced by successive scans of the laser beam along the groove. Experimental results agree well with the calculated predictions in the case of titanium alloy and tungsten carbide and for different pulse energies, repetition rates, scanning speeds, and number of scans. This confirms the validity of the model and its assumptions, and highlights the model as a useful tool for estimating groove dimensions, optimizing of process windows for machining with high depth progress, and predicting the maximum achievable groove depth.
