ABSTRACT:
A vacuum pod system for supporting a workpiece. A work table is provided with a shouldered opening formed therein in communication with a vacuum source. A pod is provided having a first longitudinal portion of a first outside diameter which seats on the shoulder in the opening, and a second longitudinal portion for supporting the workpiece, the second portion having a second outside diameter unequal to the first diameter. A passageway extends through the pod for providing communication between the first and second portions so that when the workpiece is supported on the second portion, a vacuum generated by the vacuum source creates a suction force which secures the workpiece to the pod.
