【 摘 要 】

Aiming at the problem of electrode wear during EDM, a method of instantaneous repairing EDM abrasive electrode with compensation block was proposed, taking relative mass wear as research index. The results show that diamond abrasive electrode is processed by intermittent spray cooling at 1mm / min feed rate, and the adhesion layer appears on the surface of abrasive electrode. The experimental results show that the relative wear of the electrode with compensation block is lower than that of the electrode without compensation block by comparing the relative wear value of the electrode with different speed, voltage and duty cycle for the 304 stainless steel processed by EDM abrasive electrode 0.7 times. The method of adding compensation block shows that the electrode grinding head can be compensated online to some extent.
