Abstract
A numerical control apparatus having tool cutting edge detecting unit for detecting a cutting edge position of a tool mounted on a tool rest, comprises detection signal determining unit for determining, as effective, only a detection signal that is first inputted from among a plurality of detection signals which are continuously inputted from the tool cutting edge detecting unit. A signal which is detected until a preset time is elapsed after a first signal is received when the tool comes into contact with the touch sensor, and/or until the tool moves a predetermined distance, is determined as erroneous detection by the detection signal determining unit, and the signal is disenabled.
