Abstract
Dry EDM machining with external workpiece cooling is one of the possible modifications of dry EDM process, which enables to reduce the negative impact of EDM machining on the environment and on the machine tool operator. At the same time, it is possible to obtain relatively good machining accuracy and surface quality. Due to the problems with the effective heat dissipation from the machining gap, the application of dry-EDM is still limited to micromachining. In this paper the comparison and discussion of dry-EDM technological factors for two hard to machine materials: Inconel 625 and Titanium Grade 2 have been presented. The tests were carried out in carbon dioxide as a dielectric supplied to the machining gap through the channel in the workpiece electrode. To improve the process effectivity additional workpiece cooling were also applied, however the presence of fluid in machining area makes the process near dry-EDM. The input machining parameters were pulse time, machining voltage, current amplitude and inlet gas pressure. The main aim of this work was to show the significance of the type of machined material on the material removal rate, and surface layer (i.e. roughness, morphology and microhardness). The results analysis will be discussed considering differences in physical properties of machined materials.
