Abstract

métodos e sistemas são providos para a formação automatizada de uma lâmina de vidro. os métodos compreendem o preaquecimento do vidro, curvatura do vidro através do aquecimento por feixe concentrado e seletivo através da utilização de uma onda eletromagnética de alta potência de frequência ultra alta, e processos implementados por computador utilizando dados térmicos e de forma (posicional) obtidos em tempo real, e o arrefecimento da lâmina de vidro para produzir uma lâmina de vidro adequada para uso em veículos aéreos e espaciais.
