Abstract: A machining system includes a robot arm for changing a workpiece or inspecting a machined workpiece, and a probe that is attached to a distal end portion of the robot arm via a force sensor, where the robot arm is controlled such that the probe is arranged at a predetermined measurement position in contact with a side surface of a tool holder, where detection values of the force sensor are obtained over a predetermined period of time in a state where a main spindle is performing rotation operation, where an attached state of the tool holder is determined based on the detection values obtained over the predetermined period of time.

Abstract: A pallet device which can prevent a hook fixed to a pallet from interfering with a workpiece or a tool for a machine tool. The pallet device includes a pallet including a pallet main body which clamps a workpiece, and a replacement hook movably provided in the pallet main body, the replacement hook being movable between a projection position at which the replacement hook projects outside the pallet main body and a retraction position to which the replacement hook is retracted from the projection position to the pallet main body, and a jig to and from which the pallet is attached and detached.

Abstract: A robot system which can adjust the position of a coolant nozzle at a lower cost, that is, a robot system which comprises a robot, a robot controller which controls the operation of the robot, and a notification part which notifies the type of the workpiece which is processed by the machine tool to the robot controller. The robot controller determines the target position of the coolant nozzle with respect to the workpiece to be processed based on the type of the workpiece which is obtained from the notification part and makes the coolant nozzle move by the robot so as to place the coolant nozzle at the target position.
