Abstract
Disclosed are embodiments of a vacuum chuck. The vacuum chuck includes a forming surface having a first longitudinal end, a second longitudinal end, and a curved region. The first longitudinal end and the second longitudinal end define a longitudinal axis, and the curved region defines a radius of curvature along the longitudinal axis. A plurality of elongate grooves are formed into the forming surface in the curved region. Each elongate groove of the plurality of elongate grooves has a length, a width, and a depth extending into the forming surface. The length of each elongate groove is greater than the width. At least one conduit is configured for connection to a vacuum source and is disposed beneath the forming surface. The at least one conduit extends transversely across the plurality of elongate grooves, and the at least one conduit is in fluid communication with the plurality of elongate grooves.
