Abstract: A protective structure for a vehicle having an opening on an upper surface is provided. One embodiment of the invention has at least a partial enclosure around an area defined laterally by the vehicle opening with an overhead and side protective capability. An embodiment of the invention has an overhead cover that is formed to substantially enclose a top area of the enclosure and having multiple panels that may be locked into place or opened by an occupant for exit through a top area of the enclosure. Biasing devices may be provided to bias the panels toward an open position and thereby facilitate occupant egress. The multiple panels in this embodiment extend upwardly and inwardly from a section of the enclosure's side walls. Ballistic windows are provided on the protective structure such that an occupant can view laterally and vertically through the enclosure and overhead cover. A shield or protective plate can be mounted on one side of the enclosure.

Abstract: A method for machining a blank includes machining a first pocket in the blank having a first sidewall, machining a second pocket in the blank, machining a groove within material located between the first and second pockets to expose a second sidewall opposite the first sidewall, machining the first and second sidewalls, and alternately repeating machining the grove and the sidewalls to step mill the groove deeper in the blank and form a third pocket along which the second sidewall extends.
