| Zusammenfassung: | The invention relates to a numerical control device, a numerical control method and a numerical control program capable of detecting cutter abnormality. The numerical control device determines whetherthe command of the numerical control program is speed control or position control. When the numerical control device determines that the command is position control, the numerical control device determines whether the motor is in an acceleration/deceleration state or a constant speed state on the basis of the acceleration information. When it is determined that the command is speed control, the numerical control device determines whether the motor is in an acceleration/deceleration state or a constant speed state on the basis of the speed information and the measurement information. The numerical control device detects current flowing to the motor. When it is determined that the motor is in a constant speed state, the numerical control device determines whether a cutter is abnormal or noton the basis of the detec |
