A precise EDM method based on the tangential rotary feed method of disc electrode is proposed. Firstly, the design principle of the disc electrode based on the principle of isoscelesis loss was introduced. Then by the three-factor full-factor experiment of EDM, the effect of peak current, pulse width and duty cycle on the material removal ratio (MRR) and relative electrode loss Rate (TWR) and surface roughness (SR), and the EDM process parameters to optimize the application of tapered rod parts processing. The processing performance of the feedback rod is high, the surface quality is good and the processing time is short. The experimental results show that the EDM technology based on the tangential rotation of the disk electrode can improve the reliability and processing of the processing technology of the low-rigidity cone Efficiency, improve electrode utilization has greater advantages.
