New in cutting process

It is shown that cutting is an explosion modification, and the data confirming this statement are given. New concepts of deforming and destruction at cutting are presented; a combined physical-technological model of the process of chip formation and formation of surface layer quality is elaborated. A new version of classical "σ_i - ε_i-diagram, namely, diagram of large deformations for dynamic destruction is proposed. A common mechanism of formation at metal cutting of chip of any type is theoretically substantiated. It is shown that physics of high dynamic pressures can serve as a research basis for machining by cutting.
