Abstract

A novel dry electrical discharge micro-grinding (EDMG) method was proposed to grind tungsten carbide in this paper. The V-shape tip truing experimental setup was built to realize the precision truing of diamond grinding wheel micro tip. The trued V-tip diamond wheels after mechanical truing and dry ECD truing were employed to fabricate micro-groove structures on the surface of tungsten carbide. The machining qualities and topographies of V-groove machined by dry EDMG under different pulse discharge parameters were comparatively investigated. The experimental results indicated that the dry EDMG could effectively improve the machining quality of micro-structured surface against dry mechanical grinding. However, the worn of micro tip of diamond grinding wheel in dry EDMG was faster than the one in dry mechanical grinding. The appropriate pulse discharge parameters were duty cycle dc=10%, open-circuit voltage E=15V and pulse frequency f=5000Hz in dry EDMG of tungsten carbide.
