Research of Layered Machining Experiment by Micro-EDM

Abstract:

The effect of electrode wear is significant on machining quality, in order to ensure the processing precision of micro-EDM milling, need to give reasonable compensation for the tool electrode. In this paper, based on the model of fixed length compensation method to machining the micro groove with micro-EDM by layered milling experiment, moreover, adopted the orthogonal machining path and the machine vision technology to obtain the stable end of the electrode image after processing, and then determine the reasonable path of trajectory overlap. The experimental results show that, the electrode compensation model can availably compensate the electrode wear, and the processing time is shortened by 50% with the machining method of orthogonal trajectories, and the method can make the residual cut remove obviously, gained good machining precision. We observe the bottom section linearity of micro groove is very good and the processing error of the micro groove depth is about 2 μm by the optical microscope.
