1. A system comprising a machine tool and a tool information setting device for setting tool information for use in machining by the machine tool,
wherein the machine tool comprises:
a turret including on a circumference surface thereof a plurality of turret faces, the turret configured to be turned by a turret turning motor and to be moved by a turret moving motor;
a plurality of tools respectively mounted on the plurality of turret faces each provided on the circumference surface of the turret through a tool holder according to machining, each of the plurality of tools configured to be rotated by a tool driving motor; and
a controller configured to execute a machining program, the controller including a motor controller configured to control a driving mechanism comprising the turret turning motor, the turret moving motor, and the tool driving motor,
wherein the tool information setting device comprises:
a first storage configured to store a tool holder number for distinguishing a tool holder and tool information of a tool of the plurality of tools mounted on the tool holder, the tool holder number associated with the tool information;
a second storage configured to store a turret face number for distinguishing a turret face of the plurality of turret faces and the tool holder number of the tool holder mounted on the turret face, the turret face number associated with the tool holder number; and
a tool information setting portion configured to acquire the tool holder number from the second storage based on the turret face number described in the machining program, to acquire the tool information of the tool from the first storage based on the acquired tool holder number, and to control the driving mechanism based on the tool information by sending the acquired tool information for use in the machining to the motor controller when the controller executes the machining program, and
wherein the motor controller indexes the turret face by turning the turret with the turret turning motor based on the turret face number described in the machining program to select a predetermined tool by the turret face number of the turret face on which the predetermined tool is mounted.
