Abstract

PURPOSE: To make a confirmation of the hole position precision optionally operable while in a processing cycle, by making the position precision of a hole, with a work completed, automatically confirmed by using a contact detecting measuring piece, when commanded a confirmation of the hole position by NC program.
CONSTITUTION: With a coil 20 excited by an AC power source 19, a current is induced in an induction current path (as shown by broken line in the drawing) by a contact between a hole, provided in a work W, and a measuring piece TS, and this induced current is detected by a contact detector circuit 3, with its output fed to a NC device main unit 2 to control servo motors 14W16. In the above device is additionally provided a hole position approval device 4. This device 4, when generated an spproval command for the hole position, moves the measuring piece Ts in the direction of X and Y axis until contacted to the side face of the hole, with a movement distance of the measuring piece toward each axis direction measuring eccentricity amount between virtual and actual center of the hole, and the constitution is made so to feed out an anomalous signal with its eccentricity amount when not within a permissible range.
