A computerized positioning and cutting apparatus and method for automatically cutting structures to predetermined lengths with a minimum amount of scrap for a given project. The apparatus includes a frame and a positioning trough supported by the frame. A magazine is mounted to the frame, which is sized to receive uncut lengths of structure to be selectively fed to the positioning trough. A drive system is mounted to the frame and connected to a positioning system for positioning the uncut structures in the trough. A cutter is mounted on the frame to cut the structures as the positioning system feeds the structures through the trough. A controller having an associated computer system is in electrical communication with the drive system and the cutter. The computer system calculates the optimum number of cuts per a predetermined uncut length of structure to produce a minimum amount of waste structure for the project.
