Abstract

The spark erosion metal working process demands, apart from working gaps from 10 to 100 μm and a dielectric working fluid (deionized water or hydrocarbons) also electrical discharges (sparks) with a pulse operation frequency of 10 kHz to 1MHz. The course of this process is dependent on the physical and electrical properties of the working fluid, which can be influenced by adding certain additives. In this paper the influence of alicyclic and aromatic compounds for the ignition stage are presented. For these compounds, nonpolar and negative-inductive components were analyzed specifically in their ignition behavior.
