During machining of a workpiece, a gripping force adjustment device takes into account the state of the machining and the state of the workpiece in order to set a more appropriate gripping force. The gripping force adjustment device acquires data indicating a machining state implemented by a machine tool and data relating to a gripping state realized on the workpiece by a jig, and creates data to be used in machine learning on the basis of the acquired data. The gripping force adjustment device then executes machine learning processing relating to the gripping force exerted on the workpiece by the jig in the environment in which the machine tool machines the workpiece on the basis of the created data.

A clamp installation apparatus includes a robot arm pedestal having a rotary table; a robot arm installed on the rotary table of the robot arm pedestal and having a plurality of arms and a plurality of joints; a robot hand installed to a forefront arm of the plurality of arms; and a control device. The robot hand includes: a clamp holding section configured to hold the clamp; a fastening section configured to fasten an engaging section of the clamp to give a clamp force to a work; and a measuring section configured to collect position data of a predetermined member of the clamp. The clamp can be automatically installed and removed. Also, the heat curing can be carried out in the condition to have installed the clamp.
