Parametric study of non-contact magnetic cutting

摘要

Non-Contact Magnetic Cutting is a potential manufacturing process that uses repeated, low-energy magnetic pulses to produce and direct fine cuts in metal plates or foils. The process is based on the magnetic saw effect [1],[2] which, when not controlled, can lead to failure in high-field pulsed conductors. By limiting energy and pulse duration, the authors have produced controlled cuts with kerfs as fine as 0.013 mm. These promising results motivated a systematic study of the parameters that govern the quality and reproducibility of magnetic saw cuts.
