ABSTRACT:
A detecting apparatus for machine tools with rotating spindles having adapter for holding tools such that when any of the tools engage an obstacle such as another broken tool or a workpiece, a signal is generated and is transmitted to a timer activated for predetermined periods of time during selected phases of operation. The timer is responsive to the presence or to the absence of a signal during its active period to continue or to discontinue the cycle of machining operations.
