Abstract
A controlled atmosphere machining process which involves a work station for machining a workpiece with an inert gas in an enclosed environment which will not support combustion. The process further includes a vacuum system which removes particulate matter occurring during the machining process and transports the matter to a collecting tank. The inert fluid is recycled through a filter and cooling system and continues to be drawn by the vacuum system into the enclosed machining area of each work station.
