Abstract
Proposed are an apparatus and a method of manufacturing a shell for a resonator using a laser. According to the apparatus and method, it is possible to stably manufacture 3D shells for a resonator in various shapes by applying heat through a laser and adjusting the degree of vacuum in a forming frame, it is possible to improve work safety and work efficiency, and it is possible to use various materials that are heated and deformed by a laser other than a glass material, thereby being able to increase generality of manufacturing. In particular, it is possible to accurately implement 3D shapes of a shell for a resonator such as a hemisphere or a semi-toroid, so it is possible to remarkably reduce a defective portion in manufacturing and the manufacturing cost, and considerably improve productivity.
