The mathematical and physical model of cutting of food products is conducted. It is shown out mathematical model which determines dependence of cutting effort on the parameters of regimes of process and structurally mechanical properties of product. Modeling is conducted both for homogeneous products and multi-layered which have a thin, but strong shell, here is a rapid change of cutting effort. At a physical model explored of cutting on the devices of pendulum type, that allows easily to change the parameters of regimes and cutting terms. Certainly cutting effort and rational terms at which spending energy go down and cutting quality rises. Results are applied at development of construction of equipment for cutting of food products.
