Modelling the laser fusion cutting process: I. Mathematical modelling of the cut kerf geometry for laser fusion cutting of thick metal
TL;DR: In this paper, a model for calculating the three-dimensional stationary geometric shape of the cutting front for laser fusion cutting is presented, which relates the cut kerf geometry with the cut-through depth, various laser parameters such as power, speed, focus position and material thickness.
