Streszczenie

The paper presents a brief study of electro-discharge mechanical machining with an elastic, discrete electrode. The factors causing the chemical composition and surface roughness of superficial layer have also been taken into consideration. Attention has also been given to the relation between the material of electrode and the superficial layer composition. The superficial layer obtained by BEDMM consist of several layers. At the top, a molten and resolidified laver, called recast layer, is observed. This layer is usually present because material removal in BEDMM is mainly based on melting process of the workpiece material. In the recast layer in machining condition the mixing and diffusion of the material hot electrode and the workpart can occur.
