Influence of the Magnetic Field on Cutting Edge Surface Morphology Under Lubricated Conditions

This study investigates the impact of magnetic fields on tool wear and surface morphology during lubricated turning of XC38steel ,Experiments were conducted under varying magnetic field intensities (0, 5.5, 16.5, and 28.5 kA/m). The findings revealed that tool wear was significantly reduced at 16.5 kA/m, indicating improved machining conditions. Surface roughness improved under magnetic influence due to enhanced chip evacuation and better lubricant alignment. EDX analysis demonstrated increased spectral clarity at higher magnetic fields, suggesting improved detection of tool material composition. Roughness parameters initially rose at moderate field levels, enhancing lubrication retention, and later stabilized at higher intensities. Surface morphology also improved, with less wear depth and smoother profiles. The results highlight an optimal magnetic field range for reducing friction and extending tool life. Applying magnetic assistance proved to be a simple and cost-effective method for enhancing machining efficiency.
