4-axis micro ED-milling of micro 3D structures on cylindrical workpiece based on CAD/CAM commercial software

This paper presents a correlation of the commercial CAD/CAM software into the micro 4-axis electrical discharge milling (ED-milling) process. By applying the commercial CAD/CAM software, the model can be designed and the NC code can be generated. According to the NC code, the 4-axis ED-milling process can be carried out successfully by the micro 4-axis machine tool on the cylindrical workpiece. The milling process was presented and the tool electrode wear was shown in the diagram. The on-line CCD and SEM pictures of the 3D micro structure on the cylindrical workpiece were shown in the paper at last.
