The design and fabrication of a piezoelectric micro actuator on a silicon diaphragm is presented for application of micro ink jet. We developed the micro devices for the fluid transference that are fabricated using thick film technologies for ceramic materials and Si micro-machining. The performance of drop ejection was shown from the optimal design parameters. It is closely related to the prec...

Wire EDM is one of the latest advanced micro-machining techniques, where a thin wire (Ǿ= 0.25 mm) of tool electrode is fed on the work piece which gradually shears off the material during the machining process. This micro-machining process may help overcome the limitations and restriction faced during conventional mechanical machining process. This paper is based on wire-EDM machining of a part...

This research proposes an optimized magnetic abrasive machining process that uses an ultra-high-speed system to perform precision machining on a workpiece. The system can process several microns of material, either for machining surface roughness or for machining a workpiece for a precise micro-diameter. The stainless steel workpieces have been machined using an ultra-high-speed magnetic abrasi...

Micro Electric Discharge Machining is a nontraditional machining process which can be used for drilling micro holes in high strength to weight ratio materials. This present research study deals with the single optimization of micro EDM process using Genetic Algorithm. Mathematical models using Response Surface Methodology (RSM) is used to correlate the response and the parameters. The desired r...

The e-glass fibre epoxy composite is a nonconductive ceramic material hence it is difficult to machine by any well known non-conventional machining methods like electrical discharge machining, wire electrical discharge machining etc. This material can be machined with conventional machining but compromise with accuracy, surface texture even not possible to micro slicing etc. Keeping in view, a ...

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 ...

When viewed from the size of workpieces to be cut, there are only a few machine tools that are positioned between machining centers and large machines. Therefore medium-sized workpieces are often cut by large machines. However, as the tolerance requirements for such workpieces cut by large machines have become tighter and it is difficult to achieve such tolerance only with machine performance, ...

in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...
