ABSTRACT:
Disclosed is an apparatus for automatically detecting the position of a cutting tool in a computerized numerically controlled lathe which is capable of preventing over-load operation of a driving motor by allowing an arm having a touch sensor mounted thereto to safely stop at a position while the driving motor stops operating. The touch sensor is pivoted by means of a gear assembly driven by the driving motor. When the arm is rotated and reaches a proper position, a worm and a worm wheel of the gear assembly are rotated until a camshaft is brought into contact with a stopper. The arm is moved toward the cutting tool and the cutting tool is brought into contact with the touch sensor in accordance with a program that is preprogramedly input into the computerized numerically controlled lathe.
