The performance characteristics depend on the structural steel phi physico-mechanical properties of the material. Destruction of products starts with the on-surface layers. The microstructure of the surface layer is formed by a techno-logical operations machining. Formation of the surface layer with its own physical-mechanical-stvami occurs during the manufacturing process. In the implementation of pla-plastic deformation energy consumed, 75-90% of which is irreversibly converted into heat, and 10−15% is absorbed by the crystal lattice. The most capacious physical characteristic, reflecting energetiche-mechanical state of a solid surface is the electron work function (RWE). RWE actuated by contact strained metal-dependent electric fields of contact, providing significant adge-Zia, and hence the electrostatic friction component. In this paper, the task was to evaluate the change of regimes RWE me-mechanical treatment. As the object of the study samples of structural steels X12M were chosen, 40X, steel 45, Article 3. Each sub-material subjected to machining on vertical milling machine Mini Mill 450 Machining Centre carbide end mill in the range innings S of 0.2 to 1 mm / rev. The analysis showed the identical nature of the effect of feed rate on the order of RWE were, different grades of steel. The authors suggest that the reduction in value due to the increase of spending RWE works to form the surface into heat due to the increase of power parameters with increasing supply.
