Numerical control system, and industrial machine control method

A numerical control system comprising:

• a numerical control device configured to control operation of a machine tool, and generate a robot command for controlling operation of a robot;
• a robot control device configured to be communicable with the numerical control device and control operation of the robot based on the robot command;
• a robot command generation unit configured to generate, based on a numerical control program including a plurality of robot command blocks for the robot, the robot command for each of the robot command blocks;
• a robot program launch command unit configured to generate a program launch command;
• a first communication unit provided to the numerical control device and configured to send the program launch command to the robot control device, after bundling in advance a plurality of the robot commands generated based on a plurality of the robot command blocks belonging to a designated block range as a robot command group and sending to the robot control device;
• a second communication unit provided to the robot control device and configured to receive the robot command and the program launch command;
• a robot program generation unit configured to generate a robot program based on the robot command received by the second communication unit;
• and
• an operation control unit configured to, in response to receiving the program launch command by the second command unit after the robot program is generated based on the robot command group by the robot program generation unit, launch the robot program, and control operation of the robot based on the robot program,
• wherein the first communication unit is configured to switch between
• batch processing, which sends the robot command group composed of a plurality of the robot commands to the second communication unit and then sends the program launch command to the second communication unit, and
• sequential processing, which sends one robot command and program launch command to the second communication unit for every one robot command block.
