Abstract (English):
This paper represents the results generalization of theoretical investigations in the matter of an electro-erosion processing impact upon operating properties of die mold shaping parts. A basic problem is wear-resistance and fatigue strength support at the electro-erosion processing of the products of these types. The analysis carried out has shown that the processing modes and a coefficient after an electro-erosion processing influence fatigue strength. A wear-resistance index is defined both by processing modes, and physical-mechanical properties of blank material. To ensure product operating characteristics a physical situation of complex parts processing should be defined through the choice of optimum modes for electro-erosion processing.
