Impact of Machined Surface Quality Level on Electrical Energy Consumption in WEDM

Abstract:

Increasing the quality of machined surfaces in wire-electrode electrical discharge machining (WEDM) is undoubtedly reflected in the increase in the consumption of electrical energy required to perform the electrical discharge process. The relationship between these two input-output parameters is based on the physical nature of the given process, while the surface quality and the energy intensity of the electrical discharge process are closely linked. At the same time, it is true that with the increasing quality of the machined surface, the electrical energy consumption of individual subsystems and auxiliary devices of the electrical discharge machine also increases in almost all cases. The reason is mainly the fact that the machining time is extended. This is mainly caused by the need for a larger number of passes but also higher demands on the stabilization of the electrical discharge process. Therefore, the aim of the research was to identify and describe the mutual relationships between the quality of the machined surface in WEDM and the total consumption of electrical energy required to perform the machining process.
