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 ...

Motivated by their functional conformity, micro-cantilever-based MEMS oscillators are investigated in this study as structure-integrable transducers for the acquisition of guided ultrasonic waves fiber–metal laminates. While acceleration-sensitive limited maximum frequency, presented displacement-sensitive oscillator is operated quasi-free fashion a seismometer, making it particularly sensitive...

The FEM analysis of ultrasonic tool has been done in addition to surface roughness of machined samples using ultrasonic machining process have been presented. The experimental conditions were designed by using DOE approach. The analysis of results has been done using the MINITAB 14.0 software and results obtained are validated by conducting the confirmation experiments. The F-test and P-value h...

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...

There is a huge demand in the production of microstructures by a non-traditional method which is known as Micro-EDM. Micro-EDM process is based on the thermoelectric energy between the workpiece and an electrode. Micro-EDM is a newly developed method to produce micro-parts which in the range of 50 μm -100 μm. Micro-EDM is an efficient machining process for the fabrication of a micro-metal hole ...

In order to study the influence of spindle speed and amplitude on surface integrity, TC18 titanium alloy samples were milled by process conventional milling longitudinal ultrasonic vibration assisted milling. The experimental data obtained dynamometer, thermometer, scanning electron microscope, X-ray diffractometer, three-dimensional topography instrument for observation analysis. results show ...

Electrochemical discharge micro-machining (micro-ECDM) has the ability to machine electrically nonconducting materials as compared with different existing traditional and also non-traditional machining processes. This paper deals with the effects of different process parameters like applied voltage (V), electrolyte concentrations(wt%), pulse frequency and duty ratio on different machining perfo...

Rotary ultrasonic machining (RUM) is a relatively low cost and environmentally benign process for machining of advanced ceramics. Much effort has been made to theoretically and experimentally investigate material removal rate, surface roughness, and tool wear in RUM. However, there is no report on systematic study of edge chipping in RUM drilling of ceramics. This paper presents the results of ...
