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.
1. 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.
2. The numerical control system according to claim 1 , wherein
the numerical control device determines whether or not it is necessary to acquire the configuration information during execution of the second numerical control program,
upon determining that it is necessary to acquire the configuration information from the robot control device, the numerical control device transmits a predetermined request signal to the robot control device, and
in response to reception of the predetermined request signal, the robot control device acquires the configuration information, and transmits the configuration information to the numerical control device.
3. The numerical control system according to claim 2 , wherein
in the second numerical control program, a position and a posture of the robot are able to be specified in a rectangular coordinate format or a joint coordinate format, and
in a case where the rectangular coordinate format is designated in accordance with the second numerical control program, the numerical control device determines it necessary to acquire the configuration information from the robot control device.
4. The numerical control system according to claim 3 , wherein
in a case where the rectangular coordinate format is designated in accordance with the second numerical control program and the configuration information is identified in accordance with the second numerical control program, the numerical control device determines it unnecessary to acquire the configuration information from the robot control device.
