- Abstract
The dry electrical discharge dressing and truing technology was proposed to realize the high efficient and precise truing of diamond grinding wheel in this paper. Firstly, the V-shape tip of diamond grinding wheel was formed using dry electro-contact discharge (ECD) truing along setting crossed V-shape interpolation path. Secondly, the influence of different pulse discharge parameters on V-tip angle and V-tip radius was investigated, respectively. Finally, the trued V-tip diamond wheel was employed to fabricate micro-groove and micro-pyramid array structures on the surfaces of two hard and brittle materials by micro-grinding machining. The results indicated that the optimal pulse discharge parameters were open-circuit voltage E of 5V, pulse frequency f of 4000Hz and duty cycle dc of 50%. The least V-tip angle error and radius of trued SD600 V-tip diamond grinding wheel was 1.1º and 33 µm, respectively. The micro-groove and micro-pyramid structures with regular shape and smooth surface can was effectively machined on the surfaces of difficult-to-cut materials.
