ABSTRACT

ABSTRACT: In this paper, the grit trajectory model of grinding engineering ceramics in axial deep creep-feed grinding with small grinding wheel is established and the relationship between cutting parameters and the law of diamond grits’ motion is revealed. The relation between feeding speed and the crushing of edge, grinding force and the diamond grit wear was analyzed according to the actual machining of ceramics by changing processing parameters, and the experimental results are consistent with the simulation results. Experiments is based on appropriate experimental schemes and force measuring system, the changing of the diamond grain’s curve radius was real-time detected by edge detection and curve fitting of profile. This paper also provides references on how to use the feed speed that is reasonable to enhance the processing efficiency by removing ceramic chunks via the splitting and to reduce the damage on the workpiece and the grinding wheel.
