METHOD AND DEVICE FOR MACHINING BY ENERGY BEAM

摘要

PURPOSE: To provide the method and device that has a high degree of freedom in making patterns and that is capable of freely and precisely machining a curved or slant face of an arbitrary pattern with a simple structure and also to provide an element thus manufactured with excellent performance. CONSTITUTION: The machining method by an energy beam is such that an object 2 to be machined is irradiated, through a shield 4... having a prescribed pattern, by an energy beam emitted from an energy beam source 1, and that projecting and recessing parts are formed on the surface by emitting the energy beam while at least one among the energy beam source 1, shield 4 and object 2 is relatively moved against the others and thereby controlling the beam irradiation time on the surface of the object to be machined.
