Abstract: The paper introduces the working principle of free abrasive multi-wire sawing technology and the concept of elasto-hydrodynamic interaction, and summarizes the theory research status of slurry actions in free abrasive slicing using multi-wire sawing. The theory research involves establishing mathematical model of elasto-hydrodynamic interaction, demonstrating the pressure and film thickness distribution rules using numerical method, and so on. The experiment research involves film forming state of the slurry, the influence of vibration on cutting efficiency and the influence of composition of the slurry on cutting effect and efficiency etc. The research results are helpful to further research and applications of the technology.
