ABSTRACT:
An annular frame having a biased target plate thereon is mounted in a selected path of advance of each of the usual plurality of tools of a N.C. machine. Two micro-switches are mounted for operation in sequence upon selected movement of the target plate by each advancing tool. Actuation of the first of these micro-switches slows the advance of the tool, while actuation of the second arrests tool advance and notifies the computer of the N.C. machine that such tool is then in a selected, zero position, from which position all further computer controlled operations of the tool are programmed.
