Connection of electrodischarge machining with ultrasonic assistance may cause a better result of machining mainly by increasing the machining efficiency and increasing surface quality because of improvement in erosion products transportation. In the paper the test stand for electrodischarge machining (EDM) supported by electrode tool (sonotrode) ultrasonic vibrations (USEDM) is presented. The test stand was built on the base of electrodicharge machine tool EDEA 16, which was equipped with a special ultrasonic head and tooling for workpiece clamping. The comparison of technological indicators such as: metal removal rate, surface roughness, for different values of pulse time, current amplitude and amplitude of electrode-tool ultrasonic vibrations has been dove.
