We present analytical and computational models used to investigate the dependence of etch resolution on pulse duration, tool radius, and etched feature aspect ratio in electrochemical machining with ultrashort voltage pulses. Our results predict that, for the high aspect ratio system in which the effect of trench top and bottom edges can be ignored, the increase of etch resolution with pulse le...

The fabrication of ultramicroelectrodes (UMEs) for analytical electrochemical applications has been explored, using boron-doped diamond as the active electrode material in an insulating coating formed by deposition of electrophoretic paint. Because of the rough nature of the diamond film, the property of such coatings that is normally exploited in the fabrication of UMEs, namely the tendency to...

Electrochemical spark machining (ECSM) is hybrid machining process which is the controlled removal of metal by anodic dissolution as well as erosion in an electrolytic cell in which the workpiece is the anode and the tool is cathode. The experimental investigation with the developed TW-ECSM set-up has been needed to understand the behaviour of the process parameters on performance characteristi...

As a nontraditional processing technology, electrochemical discharge machining (ECDM) can process glass and engineering ceramics precisely. This technology has proven to be potential for 3D microstructure. However, the key expanding application of ECDM is how improve accuracy. research conducted micro-hole microgroove machining. Power voltage frequency influence on hole efficiency, entrance dia...

New trends and the effect of key factors influence the quality of the holes produced by ECM processes. Researchers developed a fuzzy logic controller by adding intelligence to the ECM process. Maintaining optimum ECM process conditions ensures higher machining efficiency and performance. This paper presents the development of a fuzzy logic controller to add intelligence to the ECM process. An e...
