Controller for controlling machine tool and robot
A controller for controlling a machine tool and a robot includes a storage unit, configured to store an input machining program including a statement for machine tool and a statement for robot, and a machining program distribution unit configured to transfer the statement for machine tool, out of the statements for machine tool and statements for robot that are included in the stored machining program, to the machine tool control unit and to transfer the statement for robot to the robot control unit.
1. A controller for controlling at least one machine tool and at least one robot, the controller comprising:
a machining program storage unit configured to store a machining program input to the controller, wherein the machining program includes at least one statement for machine tool and at least one statement for robot; and
a processor configured as:
a machine tool control unit configured to control the machine tool based on the statement for machine tool;
a robot control unit configured to control the robot based on the statement for robot; and
a machining program distribution unit configured to transfer, out of the statements for machine tool and for robot that are included in the machining program stored in the machining program storage unit,
the statement for machine tool to the machine tool control unit, and
the statement for robot to the robot control unit;
wherein the machining program distribution unit comprises a simultaneous start unit configured to transfer the statements for machine tool and for robot, included within a range previously specified by the machining program, to the machine tool control unit and the robot control unit, respectively, and then simultaneously perform instructions of start of control based on the transferred statements to the machine tool control unit and the robot control unit, whereby the machine tool and the robot are simultaneously caused to start to be controlled by the simultaneous start unit.
2. The controller according to claim 1 , wherein the machining program distribution unit comprises a waiting unit configured to wait until the completion of both the control by the machine tool control unit based on the statement transferred thereto and the control by the robot control unit based on the statement transferred thereto, whereby, after the end of the control of both the machine tool and the robot is awaited by the waiting unit, the next control is performed.
