Recent innovations in the area of electrochemical micromachining (μECM) have created a unique opportunity for fabricating microproducts in the micron scale. A significant constraint in attaining improved machining effectiveness in μECM applications is that of achieving the correct microtool geometry for a specified workpiece profile. This study focuses on the influences of microtool dimension on machining characteristics of electrochemical microdrilling on nickel plate. During microtool fabrication, tungsten microshafts are electrochemically etched to make desired cylindrical microtools of different lengths and diameters to investigate the effects of tool dimension on electrochemical micromachining. The shape and size of the fabricated microholes, material removal rate, machining time, and taper angle formed in the fabricated microholes are considered as response factors. After machining, the shape and size of microdrilled holes are measured and compared to tool geometry. From the experiment, it is found that the material removal rate, machining time, and the size of fabricated microhole are significantly influenced by the microtool dimension.

Abstract
Recent innovations in the area of electrochemical micromachining (μECM) have created a unique opportunity for fabricating microproducts in the micron scale. A significant constraint in attaining improved machining effectiveness in μECM applications is that of achieving the correct microtool geometry for a specified workpiece profile. This study focuses on the influences of microtool dimension on machining characteristics of electrochemical microdrilling on nickel plate. During microtool fabrication, tungsten microshafts are electrochemically etched to make desired cylindrical microtools of different lengths and diameters to investigate the effects of tool dimension on electrochemical micromachining. The shape and size of the fabricated microholes, material removal rate, machining time, and taper angle formed in the fabricated microholes are considered as response factors. After machining, the shape and size of microdrilled holes are measured and compared to tool geometry. From the experiment, it is found that the material removal rate, machining time, and the size of fabricated microhole are significantly influenced by the microtool dimension.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
