Abstract. A mechanical model of the deformation zone is developed in the form of colored magnetized metal balls moving in a geometrically similar model of monolithic drawing that provides visualization of local plastic deformations depending on the technological parameters of the drawing process. This model allows broadening our understanding about the mechanics of the process of plastic deformation. It is determined that in any type of working metals by pressure during the stable process of deformation of the stock in the stationary deformation zone «fresh layers of the stock material» come out from the inside of the deformation zone to the contact surface of the tool and stock thereby causing uneven wear of the outer surface of the finished product at constant values of the contact pressure, the coefficient of external friction and the relative sliding speed respectively to the instrument.
