Investigation on the Electrochemical Micromachining of Micro Holes with Variable Cross-Section

Abstract:

Based on the principle of electrochemical, the processing mechanism of electrochemical machining (ECM) micro holes is analyzed and discussed, the processing model is established and the quantitative relationship is presented between the machining side gap and the electrochemical machining parameters (pulse width and pulse period, pulse frequency, duty ratio, etc.), workpiece material parameters and the parameters of the electrolyte, the electric double layer equivalent circuit constant with mathematical expression. On the basis of the analysis of the effect of processing parameters on the electrochemical machining accuracy and stability, process out the variable cross-section micro hole at an appropriate processing parameters of variable pulse width.
