INFLUENCE OF ULTRASONIC SPATIAL WAVES OVER EFFICIENCY IMPROVEMENT TO WEDM PROCESS

Abstract

The paper presents results of experimental research for the processing efficiency improvement of the Wire-Cut Electrical Discharge Machines. These machines use a wire like an electrode and are abbreviated WEDM. The WEDM machines were equipped with special devices for the simultaneous ultrasonic activation of the wire electrode in two points after two rectangular directions in space. It was noticed that the ultrasound energy which was introduced in the working environment, influenced the performance parameters of the machining process. The erosion capacity variation, accuracy, shape deviation and roughness for different materials, depending on how were prescribed the technological parameters (the intensity for dielectric breakdown and the ultrasound generators power), is presented under graphic and tabular form.
