Present work aims at multi-mechanical surface treatment of Ti-6Al-4V based-miniplate implant manufactured by electrical discharge machining (EDM) for biomedical use. Mechanical surface treatment consists of consequent use of ultrasonic cleaning, rotary tumbler polishing, and brushing. Surface layers are analyzed employing scanning electron microscopy and energy dispersive X-ray spectroscopy. Al...

Experiments on Highly Oriented Pyrolytic Graphite (HOPG) demonstrate that ultrasonic-assisted actuation with the tip of an Atomic Force Microscope (AFM) cantilever can induce stacking modifications and folding of triangular-shaped HOPG surface flakes. We have generated permanent displacements of buried dislocations that require stacking changes of extended graphene layers by repeatedly scanning...

C/SiC composite material is the best choice for important parts such as hot-end structure of aerospace vehicles. Research and optimization cutting force ultrasonic vibration-assisted grinding are great significance when it comes to revealing machining mechanism composites realizing low-damage efficient machining. In this paper, comparative experimental study common carried out; variation laws r...

While ceramics are important materials for electronic and microsystem packaging, they are difficult to pattern lithographically. LEEDUS, a fabrication process combining lithography, electroplating, batch mode micro electro-discharge machining (µEDM) and batch mode micro ultrasonic machining (µUSM), is presented in this paper. This technology provides die-scale pattern transfer capability from l...

This paper reports a self-aligned three-dimensional process (3D-SOULE) that incorporates batch-mode micro ultrasonic machining (μUSM), lapping and micro electro-discharge machining (μEDM) for fabrication of concave and mushroom-shaped spherical structures from hard and brittle materials. To demonstrate the process, 1 mm structures are fabricated from glass and ruby spheres. The μEDM technique i...

Form accuracy of a machined component is one of the performance indicators of a machining process. Ultrasonic micromachining is one such process in which the form accuracy of the micromachined component significantly depends upon the form stability of tool. Unlike macromachining, a very small amount of tool wear in micromachining could lead to considerable changes in the form accuracy of the ma...
