Abstract
An exhaust system and method are adapted for use in a laser cutting device. The cutting device includes a base having a working surface for supporting a work piece thereon. A laser plotter head is mounted for movement over the working surface of the base. A laser communicates with the plotter head and directs a work piece cutting laser beam onto the work piece on the working surface. The exhaust system includes a multiplicity of exhaust ports formed in the working surface of the base. A manifold cooperates with an underside of the base and in substantially sealed fluid communication with the multiplicity of exhaust ports in the working surface. An elongated, flexible exhaust hose is connected at its first end to the manifold and at its second end to the laser plotter head. The second end is directed towards the work piece on the working surface and movable in unison with the movement of the plotter head. A vacuum is connected to the manifold for simultaneously drawing air inwardly through the exhaust ports in the working surface and through the exhaust hose. Fumes generated during operation of the laser are thereby simultaneously exhausted from an area above and below the work piec…
