On the laser-driven integrated dressing and truing of bronze-bonded grinding wheels

This paper analysed the physical process of multipulse laser ablation of a bronze-diamond grinding wheel. The analysis considered the effects of phase explosion, plasma shielding effects and energy accumulation under the pulse interval, and it includes heat transfer equations for multipulse laser ablation of the bronze-bonded diamond grinding wheel. The model was applied for numerical simulation of the heat transfer characteristics in the multipulse laser ablation of bronze and diamond. Next, experiments were conducted to analyse the topography of a bronze-bonded diamond grinding wheel after multipulse laser ablation. The theoretical analysis and experimental results showed that a multipulse laser can merge the truing and dressing on a bronze-bonded diamond grinding wheel. A comparative analysis showed that the numerical solution to the model is in good agreement with the experimental data. This study provides theoretical guidance for optimising the process parameters in the laser ablation of a bronze-bonded diamond grinding wheel. (C) 2015 Elsevier.B.V. All rights reserved.
