On some Possibilities for Optimizing the Wire Electrical Discharge Machining (WEDM) Processing of Welded Joints Applied to Stainless Steel

Abstract:

The process of wire electrical discharge machining (WEDM) of welded joints applied to stainless steel parts has raised important questions due to the effects on the machined surface and even the deep substrates. The paper proposes the possibility of improving working conditions by multiple activation of the effective processing space. The experimental research was performed under the conditions of simultaneous activation, both ultrasonic of the wire electrode and by magnetic activation of the dielectric liquid. The selection of the optimal parameters of magnetic activation was made using an experimental statistical modeling method, with a statistical analysis of the objective functions, using specialized software. The additional introduction of ultrasonic energy into the workspace has led to the rapid refresh of the dielectric fluid and the accelerated evacuation of eroded particles.
