Abstract
A rapid method of cutting thin amorphous metal sheet material is to use a focused heat source such as a laser beam or electron beam to heat local regions of the material above the crystallization temperature and form brittle crystalline lines along which the material fractures when it is mechanically deformed as by passage through a set of rollers. The material is not melted and does not form burrs. A higher packing factor is possible for motor and transformer laminations.
