摘要

The high-quality fabrication of specific micro groove structure on metal surface faces many technical challenges. In this regard, Based on Rotating Through-mask Electrochemical Transferring Technology, the influence mechanism of machining voltage, through-mask rotating speed, machining angle and machining times on the obtained micro groove structure was studied, the geometric profile characteristics, forming accuracy and surface quality was evaluated. Based on the optimization of process parameters, the single micro groove (width is 327.2±11.36μm, depth is 57.6±6.75μm, micro groove bottom surface roughness Ra is 0.41μm) and the array micro grooves (326.5μm~330.9μm in width, 48.8μm~53.1μm in depth, 0.41μm~0.43μm in Ra) were manufactured on SUS304 workpiece, the array micro grooves have uniform size distribution and high morphology consistency. Therefore, high-quality machining massive micro groove structure by Rotating Through-mask Electrochemical Transferring Technology has tremendous industrial application potential.
