Abstract :
In the given article, on the basis of the standard hydrodynamic representations, the physical model of the directed destruction of metals by cutting is offered. Process of cutting of metals is considered as process of the directed destruction, i.e. process of deep plastic deformation of metal always led up to destruction on surfaces of the cutting, defined by process kinematics. The design of the metal-cutting tool for part removal liquid-alloy (in the form of a ridge) from an internal contact zone of shaving is presented. Physicomechanical properties of ridges both their geometrical form and the sizes testify that they are formed of a stream of the melted metal owing to fast cooling in environment. Identity of mechanical properties of ridges and the modified layer on a tool surface of shaving testify to identity of conditions of their formation from liquid metal. The experimental evidence of the offered physical model is produced.
