Abstract

método para proteger uma superfície, sistema para uso na proteção de superfícies e método para usinagem a laser” a presente invenção refere-se geralmente a usinagem a laser, e mais especificamente a proteção de incidência indesejada de laser em uma peça. o método para proteger uma superfície, durante usinagem a laser, compreende dirigir um fluido (1530, 2316, 2416, 2640, 2824) para dentro de uma cavidade (318, 1522, 2118, 2326, 2426, 2430) de um objeto (112, 320, 816, 950, 1510, 1816, 2110, 2210, 2324, 2432, 3110) que está sendo usinado a laser, onde o fluido (1530, 2316, 2416, 2640, 2824) não tem propriedades de absorção de laser; e dirigir uma pluralidade de pulsos de laser (212, 324, 1512, 1612, 1613, 2332, 2420) para uma parede (114, 326, 1520) do objeto que está sendo usinado a laser, onde os pulsos de laser (212, 324, 1512, 1612, 1613, 2332, 2420) são configurados para formar um orifício (214, 330, 1518, 2112, 2113, 2212, 2213, 2330, 3114) através da parede de modo que pelo menos um pulso de laser (212, 324, 1512, 1612, 1613, 2332, 2420) passe através do orifício (214, 330, 1518, 2112, 2113, 2212, 2213, 2330, 3114) e entre na cavidade (318, 1522, 2118, 2326, 2426, 2430) enquanto o fluido (1530, 2316, 2416, 2640, 2824) é dirigido para dentro da cavidade (318, 1522, 2118, 2326, 2426, 2430) de modo que o pulso de laser seja incidente no fluido (1530, 2316, 2416, 2640, 2824) e em uma superfície juntos a fim de inibir dano a uma parede traseira (120, 332, 1526, 2116, 2216, 2428).
