Dependence of Crater Formation in Dry EDM on Electrical Breakdown Mechanism
(2016)Procedia CIRP ~ 18th CIRP Conference on Electro Physical and Chemical Machining (ISEM XVIII)The research effort in dry electrical discharge machining (DEDM) has increased during the last years. The process has advantages in comparison with EDM in oil-based dielectric media, such as low tool electrode wear, thin recast layers on the work piece surface and much more environmentally friendly conditions. However, the plasma-material surface interactions involved in dry EDM are not properly explained yet. Therefore, a characterization ...Conference Paper -
Influence of the anode material on the breakdown behavior in dry electrical eischarge machining
(2012)Procedia CIRP ~ Fifth CIRP Conference on High Performance Cutting 2012In the last years dry electrical discharge machining (DEDM) has been proposed as an alternative to the traditional EDM. The main reason for these efforts is the absence of a liquid dielectric which results in a simpler and environmentally friendly machine. This paper presents measurements of the material removal rate in function of different tool electrode and work piece material put in relation with the breakdown behavior of the process ...Conference Paper -

Development and Application of an Eco-design Tool for Machine Tools
(2016)Procedia CIRP ~ The 23rd CIRP Conference on Life Cycle EngineeringImproving the energy efficiency of machine tools is one of the challenges regarding the European energy saving goals. This work presents a new tool, enabling an effective quantification of a machine tool's (MT) energy consumption during all life phases. Scope of the presented tool is the fast and efficient estimation of a MT's cumulated energy demand and the systematic derivation of improvement measures regarding ecological performance. ...Conference Paper -
Post-Coating Treatment of Cutting Edge for Drilling Carbon Fibre Reinforced Plastics (CFRP)
(2016)Procedia CIRP ~ 7th HPC 2016 – CIRP Conference on High Performance CuttingDrilling of highly abrasive carbon fibre reinforced plastics (CFRP) requires carbide tools with geometrical highly adaptable tool geometries andwear resistant diamond coatings. To counteract the tradeoff between long tool lifetime by preferably thick diamond layers leading to largecutting edge radii (bluntness), and the sharpest possible cutting edge to generate flawless machining qualities, the following ...Conference Paper -

EDM Drilling of Non-Conducting Materials in Deionised Water
(2018)Procedia CIRP ~ Proceedings of the 19th ISEM Conference (ISEM - XIX)Electrical discharge machining (EDM) of non-conducting materials currently is only possible with the help of an auxiliary conductive layer, known as assisting electrode, which must be regenerated after each discharge. Therefore, an assisting conductive layer is applied to the surface of the workpiece to initiate the discharge process. In order to continue erosion, the eroded surface regions must have a new conductive layer in contact with ...Conference Paper
