Summary: | The magnetic field-assisted machining process is expected to be a useful post-processing technique. For surface treatment, residual stress is known to exert an influence on fatigue strength and stress corrosion cracking, and techniques to increase compressive residual stress on the processing surface and pipe inner face are required. Here, the magnetic field-assisted machining process using electrolyzed reducing water was shown to increase compressive residual stress compared to the use of the traditional approach using metalworking fluid. This study was performed to examine the basic working characteristics of the new technique that increases compressive residual stress using the magnetic field-assisted machining process with electrolyzed reducing water. Furthermore, we developed a magnetic pole incline processing method to increase compressive residual stress values and applied this method to internal processing. The results demonstrated the usability of this processing method. |
