This paper reports recent advances in batch mode micro-electro-discharge machining (μEDM) for high precision micromachining of metal alloys such as stainless steel. High-aspect-ratio silicon microstructures with fine feature sizes formed by deep reactive ion etching are used as cutting tools. To machine workpiece features with widths 10 μm, a silicon dioxide coating is necessary to passivate th...

Ultrasonic machining (USM) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. This paper addresses the concept and development of an expert system (ES) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...

Due to the widespread applications of fiber reinforced polymer composites in various industries, the machining of these materials to reach the desired shapes, close tolerances and surface finish quality is of great importance. But the composite materials are anisotropic and are mostly prepared in laminated form and, therefore, they have special chip formation behaviour. Among the effective para...

Wire electrical discharge machining (WEDM) is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004" - .012" (.10mm - .30mm) although smaller and larger diameters are available. WEDM is a thermal machining process capable of accurately machining parts with varying hardness or complex shapes. WED...

Planetary or Orbital tool actuation is one of the process improvement techniques used in Electro Discharge Machining (EDM) process which has multi facetted advantages. In present work, an attempt has been made to study the effect of various process parameters during planetary EDM of Ti-6Al-4V; a material which is difficult and expensive to machine by conventional methods. Parameters viz. Pulse ...

An experimental investigation was conducted to determine the application of die sinker electrical discharge machining (EDM) as it applies to a hybrid titanium thermoplastic composite laminate material. Holes were drilled using a die sinker EDM. The effects of peak current, pulse time, and percent on-time on machinability of hybrid titanium composite material were evaluated in terms of material ...

Mining/marine bushings, biomedical implants, and many more are among the several applications of lightweight elastomer components. The use non-traditional machining to manufacture these good-quality components in small or batch-size units is required because primary manufacturing method requires customised mould follow-up machining. In this regard, present work focuses on investigating performa...
