- Abstract
The paper reveals the technical solutions adopted on the design of an equipment used for electrodischarge machining aided by ultrasonics of microslots. Ultrasonic assistance consists of two separate independent working sub assemblies. The main ultrasonic assistance, acting at workpiece level, consists of an ultrasonic chain containing also the electrode tool. For best performance the ultrasonic generator of this chain must be synchronized with the electrodischarge installation pulse generator. A second additional system for ultrasonic assistance supplies high pressure dielectric liquid within working gap, through cavitational effect produced by an ultrasonic chain that vibrates in an ultrasonic hopper. The equipment is able to assure adjustments of perpendicularity or specific angular position for both electrode-tool holder and workpiece holder. The equipment was designed in order to extend ELER 01 Romanian electrodischarge installation capabilities.
