Dynamic Stability of the Technological Machining System in EDM

The paper presents the results of the theoretical and experimental research concerning the physical model, the transfer functions and the equations of the dynamic stability on processing in EDM. It also deals with the influence of the electrotechnological factors upon the technological oscillations, characteristic of the tool-electrode at the EDM. There is also shown the influence exerted by these technological oscillations on the productivity, roughness of the machined surface and manufacturing precision. This is e continuation of the paper introduced at CIRP 1990.
