Effect of Reference Current and Depth of Cut on Electro-Discharge Energy in Electro-Discharge Truing Process for Metal-Bonded Grinding Wheel Shin, Gun-Hwi; Kwak, Tae-Soo; Jung, Myung-Won; Kwak, Ihn-Sil;
This study focused on developing an electro-discharge truing method for the ELID grinding process using a metal-bonded grinding wheel. The truing process in grinding plays important roles in enhancing the quality of the ground surface. In this study, a reference current in the electro-discharge truing process was confirmed to be a viable solution for efficient truing through performance experiments. Current and voltage variation experiments were carried out and the variation output data were collected with a monitoring program to understand the electrodischarge phenomenon that occurs between metal-bonded grinding wheels and copper electrodes. The experimental results showed that as the reference current decreased, the average electro-discharge energy decreased. Therefore, the reference current can be used as an indicator to estimate the size of the gap between the truer and grinding wheel.
