Abstract
This paper proposes an in-process truing method for metal-bonded diamond grinding wheels in electrolytic in-process dressing (ELID) grinding. In general ELID peripheral grinding, dressing voltage is equally supplied on the periphery of a grinding wheel, so that it is uniformly dressed. In contrast, in this study, an attempt has been made to supply dressing voltage in proportion to the wheel radius by the pulse width control in order to improve the roundness of the grinding wheel. For this purpose, a wheel profile monitoring system and a pulse controllable power supply were developed and the in-process truing procedure was designed. Finally, its effectiveness was verified experimentally.
