Control system

A control system comprising:

• a machine tool controller that controls a machine tool;
• a robot controller that is connected to the machine tool controller in such a manner as to be communicable therewith and that controls a robot;
• a manual operating device that has a dial to be rotated by an operator and that generates, in response to rotation of the dial, an operation signal for moving the machine tool and the robot;
• and
• an operational-target setting unit that sets an operational target for the manual operating device selectively between the machine tool and the robot,
• wherein the manual operating device is connected to one of the machine tool controller and the robot controller and inputs the operation signal to the one of the machine tool controller and the robot controller, and
• wherein, when the operational-target setting unit sets the operational target as a control target to be controlled by the other of the machine tool controller and the robot controller, the one of the machine tool controller and the robot controller transmits the operation signal or a signal based on the operation signal to the other of the machine tool controller and the robot controller.
