Metal alloys have material properties that are very appealing for micro electro mechanical systems (MEMS), but present a challenge for process integration within a lithographic manufacturing sequence of the type used in the semiconductor industry. The batch-mode micro electrodischarge machining (μEDM) discussed here uses lithographically-fabricated electrode arrays with high density and high un...

EDM is a prominent non-traditional machining process, which is widely used for machining hard materials which is not possible byconventional processes. A very special aspect of this process is a surface modificationby material transfer from the tool electrode to the work-piece which is commonly known as electro discharge coating (EDC). In this work, electrode prepared with tungsten (W) and copp...

Aluminium metal matrix composites (AMMCs) are now gaining their usage in aerospace and automotive industries. Because of their inherent nature, difficult to machine, they find very little applications in other sectors. Even non traditional processes like Laser Jet Machining and Electro Discharge Machining result in significant sub surface damage to the work. In this paper, an attempt is made to...

This paper reports a parametric study of batch mode micro-electro-discharge machining (μEDM) of high density features in stainless steel. Lithographically fabricated copper tools with single cross, parallel line and 8 × 8 circle/square array features of 5–100 μm width and 5–75 μm spacing were used to quantify trends in machining tolerance and the impact of debris accumulation. As the tool featu...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

Electrical discharge machining (EDM) is a non conventional manufacturing process which is used for shaping hard metals and forming deep complex shaped profiles by arc erosion in all kinds of electro-conductive materials. The objective of this paper is to study the influence of process parameters and electrode shape configuration on the machining characteristics such as surface quality, material...
