Analysis of flow field in cutting zone for spiral orderly distributed fiber tool

In order to reduce the grinding temperature and improve the lubrication and cooling performance of grinding process, a spiral orderly distributed fiber tool was proposed. The simulation of flow field in cutting zone for spiral orderly distributed fiber tool and the grinding experiment were carried out. The results indicate that the useful flow of cutting fluid for the spiral orderly distributed fiber tool is increased obviously, in comparison to the traditional grinding wheel with disordered arrangement of grains. When the fiber number per unit area for the fiber tool is kept constant, the useful flow of cutting fluid is increased with increment of the fiber pitch. When the fluid jet speed or the exit height of the spray nozzle is increased, on the one hand, the useful flow of cutting fluid is increased; but on the other hand, the utilization rate of the useful flow of cutting fluid is reduced. The useful flow of cutting fluid supplying with an angle of 15A degrees on the horizontal direction is significantly higher than that in the horizontal direction. The computational model is validated by cutting experiments with a corundum grinding wheel.
