Some higher end panel saws feature computer controls that move the blade and fence systems to preset values.
Other lower end machines offer simplicity and ease of use, including full scale hobbyist level panel saws at a mere fraction of the cost.
Scoring is used to create a groove, especially in double side laminate before the main saw rips the piece in two, to avoid chipping.
