On the basis of statistical analysis of a large amount of experimental data, the processes of cutting and plastic deformation of various metal-based structural materials are considered. It is shown, that synthesis of materials and the formation of the surface layer of the product are unstable processes. The considered instabilities relate mainly to two types: knot and saddle, and their stabilization occurs in the cyclic mode of the limit cycle. For high-strength structural materials, it is proposed to intensify the processes of mechanical and physical-technical processing of materials using preheating with concentrated energy sources: electric arc, plasma, laser and others. For viscous heat-resistant materials, intensification is additionally proposed due to additional movements, in addition to the main movement of the tool. The proposed intensification has been tested and implemented in a number of new technological processes synthesis of materials of mechanical and physical-technical processing of materials.
