Modeling studies in laser cutting are the scientific ways to study the system behaviors and help us to
get a better understanding of this complex process (Syn et al., 2011). A mathematical model of a
system is the relationship between input and output parameters in terms of mathematical equations
(Dubey & Yadava 2008). Although the regression models are very promising for practical applications,
they are of limited applicatability and reliability in laser cutting modeling. Therefore, to establish a
mathematical relationship between the kerf taper angle and the laser cutting parameters, a multilayer
perceptron type ANN was selected.
