Abstract
In this study, we calculated the repulsive force of magnetic levitation for superconductive-assisted machining (SUAM) using the finite element method. Conventionally, SUAM utilizes bulk superconductors; here, we propose a magnetic levitation tool using superconducting tape. To obtain a stronger repulsive force, we fabricated various SUAM models and performed calculations. The results showed that we could obtain a strong repulsive force by arranging six superconducting tape pieces radially at equal intervals from the center of the SUAM tool, shortening the distance between the layers, and making the tape trapezoidal in shape. By increasing the number of layers, we can expect to achieve a greater repulsive force than that obtained with bulk superconductors.
