Abstract:

The methods to dress diamond grinding wheel using assistant side blowing and to measure grinding force with simplifying process were presented,in which grinding force,grinding force ratio and specific
grinding energy were computed and the comparison between the results before and after laser dressing verified the effectiveness of laser dressing from different aspects.The variation rule of grinding force was explained with surface topographies of wheel and workpiece.The results show that with assistant side blowing the phenomenon of bond re-solidification can be reduced,
the grinding force decreases 5%～7% and its grinding capability is improved effectively.
