Study on Macro/Micro Complex Feed Mechanism in Dry-ECD Assisted Truing and Dressing of Diamond Wheel

Abstract:

A novel truing and dressing method, namely dry electrical discharge (dry-ECD) assisted truing and dressing, is proposed to overcome the shortcomings associated with conventional mechanical dressing methods, ELID and ECD methods. The macro/micro complex feed mechanism in dry –ECD assisted truing and dressing equipment is designed to maintain continuous discharge between the tool electrode and diamond wheel in dry-ECD automatically. A series of basic performance experiments of the micro feed mechanism show that the position accuracy of the micro-feed mechanism is below 0.35μm using the micro-positioning control system. Whereas，the position accuracy of the mobile negative electrode is 1μm without macro/micro complex feed mechanism.
