STUDY EFFECT OF EDM-PIERCING COPY OF PROCESSING ON THE FORMATION ROUGHNESS TREATED SURFACE MATERIALS WITH DIFFERENT PHYSICAL-MECHNICAL PROPERTIES
The work is directed to the study of the formation of the roughness of processed surface of the materials with different physical and mechanical properties, depending on the EDM modes. The aim is to determine the effect of experimental conditions on the roughness of EDM electrode parts and tool electrode. A study conducted on copying broaching EDM Company Smart CNC. For the experiments using samples of Al, BT3, 40HN2MA and 09G2S. Showing obtained depending on the roughness of the electrode, parts and tool electrode at various modes of treatment. The features of the formation of surface roughness on the tool electrode and the electrode parts in the processing of the minimum and maximum modes.
