What is Cutting Kerf? Comparison of Cutting Methods | Fractory

Aug 30, 2019 · Cutting kerf is the width of a cut. It is the result of material removal during the cutting process. Almost all cutting mechanisms leave a cutting kerf, e.g laser cutting, plasma cutting and other thermal cutting methods. But also mechanical cutting processes like sawing. There are also cutting methods that lead to no loss of material.
