ABSTRACT:
An electrical machining method and apparatus in which a gaseous effluent containing noxious or unacceptable gaseous components is evolved from the electrical machining gap and is collected in a space immediately above the gap flooding electrical machining liquid and confined from direct escape into the atmosphere. This space or chamber is arranged to communicate with the atmosphere via an elongated fluid conduit for drawing the collected gases into the atmosphere. A laser generator irradiates the flowing gases with a laser beam to decompose the noxious components into their constituent elements. Mirrors for the laser beam may be vibrated to laterally oscillate the laser beam, thereby enhancing the efficiency of the laser irradiation and the resulting gas detoxification.
