Numerical control device and numerical control system

Abstract

Provided is a numerical control device in which a payload setting of a robot can be switched from the numerical control device. This numerical control device 2 comprises: an analysis unit 23 that analyzes a robot numerical control instruction in a numerical control program; a robot instruction signal generation unit 25 that generates a robot instruction signal to be transmitted to a robot control device 3 in accordance with the robot numerical control instruction analyzed by the analysis unit 23; a payload setting selection unit 24 that selects a payload setting to be set for a robot 30 from among a plurality of payload information in accordance with the robot numerical control instruction analyzed by the analysis unit 23; and a data transmission/reception unit 26 that transmits the payload setting selected by the payload setting selection unit 24 to a payload setting update control unit 38 of the robot control device 3 via the robot instruction signal generation unit 25 and thereby reflects the payload setting in an inverse dynamics calculation for torque to be input into the robot 30.
