An optimized long aspect radio micro rotary parts machining process was proposed based on common wire EDM machine. By adding a precise rotary spindle to a conventional three axis CNC wire EDM machine, it can be extended to perform the fabrication of small radius and high aspect ratio rotational components. Additionally, a high material removal rate (MRR) and a fine surface could be achieved by using a new combined feeding strategy in this machining process. A single factor experiment was conducted to investigate the influence of the radial infeed on MRR. The experimental results showed that the maximum MRR can reach up to 3.09 mm3/min when the radial infeed was 50 μm. At last, a feedback rod and a group of pin electrodes were machined by applying optimized parameters and following the new feeding strategy, and the achieved maximum aspect ratio was more than 60 among these pin electrodes.
