- In the grinding process, grinding fluid is delivered for the purposes of chip flushing, cooling, lubrication and chemical protection of work surface. Lubrication and cooling are the most important roles provided by a grinding fluid. Hence, the conventional method of flood delivering coolant fluid by a nozzle achieves high process performance. However, the flow velocity field can be generated ahead of the grinding zone due to the wedge effect between wheel peripheral surface and workpiece surface. According to Navier-Stokes equation and equation of continuity for fluid flow, the mathematical model of the velocity field in the wheel/workpiece wedge-shaped zone was established and simulated. Findings presented that the flow velocity increased as the velocity of the grinding wheel increased. At the direction of wheel width, the distribution patterns of the flow velocity were the same, expect the rising at the verge of the wheel. In addition, the experiment research on the velocity field in the wheel/workpiece wedge-shaped zone was also conducted. Findings demonstrated that the established model was consistent with the experimental results and the theoretical model effectively protected the distribution of the velocity field in the prediction contact zone.
