INFLUENCE OF SOME PROCESS INPUT FACTORS ON THE SURFACE ROUGHNESS AMPLITUDE PARAMETERS AT EDM WHEN USING TUBULAR TOOL ELECTRODES
The electrical discharge machining could be used sometimes to improve the roughness of the machined surfaces.The neflintw-r6mpw values of the surface roughness parameters are affected by the characteristics of the electrical discharges developed between the closest asperities existing on the active surface of the tool electrode and on the workpiece
