Numerical control system

A numerical control system comprising:

• a numerical control device configured to generate a machine tool command signal as a command directed to a machine tool in accordance with a first numerical control program, and a robot command signal as a command directed to a robot in accordance with a second numerical control program;
• and
• a robot control device communicable with the numerical control device and configured to control operation of the robot based on the robot command signal,
• wherein
• the numerical control device inputs the machine tool command signal to the machine tool and causes the machine tool to machine a workpiece,
• the robot control device acquires configuration information necessary for identifying an axis arrangement of arms of the robot and a rotation number of joints a of the robot, and transmits the configuration information to the numerical control device, and
• the numerical control device generates the robot command signal based on the configuration information transmitted from the robot control device and the second numerical control program.
