Research on Electrochemical Dissolution Localization in Case of Micro Machining with Ultra Short Pulses
The electrochemical micro machining (ECMM) is one of the most attractive methods for micromachining of conductive materials. The industrial application of ECMM is limited by unsatisfactory dissolution localisation (what decrease machining accuracy). In recent years, thanks to nanosecond voltage pulse application, accuracy of electrochemical micro machining was significantly improved up to micrometers range, but the machined surface is also limited to micrometers size. However, in case of microstu ctures machining with area about 1 mm2(i. e. tools for micro forming) this method is not effective, and the classical microsecond PECM has to be applied. Therefore, to find out limits of PECM accuracy the research on dissolution process localization is necessary. In the paper results of investigation carried out in order to investigate q (S)=A/Sn characteristic for microsecond voltage pulses machining have been presented. The research has been carried out for different interelectrode voltages and electrolytes. Thanks to experimental data it was possible to find out dissolution localisation factor n and estimate limits of microsecond voltage pulse machining accuracy.
