Performance evaluation of superconductive-assisted machining (SUAM) with superconducting tape and two permanent magnets

Abstract In this study, the repulsive force causing magnetic levitation for superconductive-assisted machining (SUAM) is calculated using finite element method. Although bulk superconductors have been used SUAM, here, we propose a tool that uses superconducting tape. To obtain stronger force, various models of SUAM are designed and calculated. The results show strong can be obtained by two permanent magnets. addition, even if tape rotated during stacking due to errors, not affected, indicating there no need optimize Therefore, expect increasing number layers will generate greater than with superconductors.
