Abstract: A multi-axis, computerized numerically-controlled (CNC) toolhead positioning device with six degrees of freedom of movement while utilizing only five axes of movement, comprising a rotating workpiece mount assembly (28) and a rotating gantry (64) with a mounted toolhead assembly base (80). Perpendicular rotational axes about a mounted workpiece (26) provide the capability to perform specific toolhead operations on the arcuate surface of the workpiece (26), subject to the type of mounted toolhead assembly. The computer (120) uses CNC software to integrate operator instructions, machining operations, and the sequence of operations into an automatic and coherent machining package.

Abstract: Portable vehicular barricade and vehicle disabling device consisting of three structural steel I-beams joined together at a central axis location at right angles to each other to form a large, 3-dimensional, x-shaped structure. When placed on the ground, the barricade will come to rest on three of the structural steel I-beam ends, forming a stable tripod I-beam base. The remaining three structural steel I-beam ends will be facing upwards and out from the central axis of the device. Upon impact of an on-coming vehicle, the tripod I-beam ends will dig into the ground while the steel I-beam ends facing upwards and out will tear through the vehicle's chassis and engine components, and at the same time, roll over with the vehicle's momentum to cause the barricade device to lodge itself under the vehicle, impeding any further forward motion of the vehicle, and possibly forcing the vehicle on its side or back.
