Electrochemical Micro-Drilling with Ultra-Short Pulses

Abstract:

Electrochemical micro-machining (EMM) has a high removal rate, leaves no residual stress on the surfaces of machined products, and generates a low level of roughness on the surface of machined products. In this work, a novel pulsed power generator is used to support tens of nanosecond duration to drilling. The influences of working parameters, such as pulsed duration, applied voltage, electrolyte concentration, pulse frequency, tool feed rates, and hole depth, on the hole over-cut and conicity in electrochemical micro-drilling are investigated. A high-quality micro hole with a 13.75 μm overcut is drilled into a nickel plate 300 μm thick.
