NUMERICAL CONTROL SYSTEM

A numerical control system 1 comprises a numerical control device 5 that generates a machine tool command signal as a command directed to a machine tool 2 , in accordance with a machine tool numerical control program, and generates a robot command signal as a command directed to a robot 3 , in accordance with a robot numerical control program, and a robot control device 6 that is capable of communicating with the numerical control device 5 , and controls an operation of the robot 3 on the basis of the robot command signal. The robot control device 6 acquires form information that is information necessary for identifying the form of the robot 3 , and transmits the form information to the numerical control device 5 . The numerical control device 5 generates a robot command signal on the basis of the form information transmitted from the robot control device 6 and the robot numerical control program.
