In previous studies, the improvement of the useful flow and flow rate of grinding fluid has been investigated via modeling, simulation, and experiment. Optimized grinding parameters have been achieved. A detailed assessment of the improvement in the useful flow rate of grinding fluid, which optimizes the grinding fluid supply, has been published in the International Journal of Advanced Manufacturing Technology (Li et al. Int J Adv Manuf Technol 75:1587-1604, 2014). Then, a detailed experimental study on the improvement in the useful flow rate of grinding fluid has been published in the Interna...
