ABSTRACT:
An automatic reconfigurable die having an array of knives, each of which is separately pivoted and extended along and about a respective longitudinal axis, to allow a desired contour to be scored and cut from a sheet material, according to a real time computer plan which is controlling the array of knives. The automatic reconfigurable die includes actuators associated with each knife to control, via information associated with a remote computer system, the extension and retraction, and orientation of the knives. The computer selects the appropriate setpoints for each knife in order to match the required shape/pattern of the cut by simple curve fitting methods. In this manner, a selected plurality of the knives in the array are chosen, oriented and extended in real time to score/cut the selected part.
