Process Research on High-Speed Small Hole Drilling by EDM Combined with Magnetic Field and Water Dispersant
The mechanism that the magnetic field and the dispersant are helpful to chip removal, to improve the material removal rate (MRR) and to reduce the tool wear rate (TWR) was analyzed in detail.The corresponding experiments were conducted based on theoretical analysis. The experimental results show that adding a certain proportion of dispersant into the dielectric fluid and introducing the magnetic field for high speed small hole drilling by EDM can greatly improve the material removal rate and significantly decrease the tool wear rate.
