“…Recent work [14][15][16][17][18] has demonstrated the ability to metalcutting by combining electromagnetic and mechanical forces. The magnetic saw effect, induced by the Lorentz force generated due to the application of a series of electromagnetic (EM) pulses, can be utilized to cut a metallic component containing a pre-existing cut or crack.…”

PLASTIC DEFORMATION ZONE IN ELECTROMAGNETIC CUTTINGThis paper presents the application of the electromagnetic field as a tool for metal sheet cutting. The experiments showed that one can easily adapt the conventional cutting equipment to the electromagnetic cutting technology and thereby eliminate the mechanical work of the punch and the press. Two methods exploiting the electromagnetic field as the tool for cutting sheet metal were used. In one of the methods the cutting element was a die while in the other method a punch was used for cutting. Owing to the high quality surface of the cut obtained by each of the methods the cutting process does not entail additional costs for removing burrs. The shape of the surface of the cut is different than the one obtained by traditional blanking -no zones characteristic of the latter are present here. In the case of both materials, the rollover of the sheet surface is much larger and longer than in the conventional method. In comparison with the conventional method, the electromagnetic machining technology ensures high quality of the surface of the cut and can be successfully used in the industry.
