A control device of a machine including: an operating condition analyzing unit that analyzes an operating condition of the program, and performs a notification when the tool to be exchanged is not adjusted; an operating condition storage unit that stores the operating condition of the program at a time of exchanging the tool; a state restoration confirming unit that confirms whether an internal state of the machine and/or the control device is restorable so that an operation of a predetermined block of the program is performed again after the operation and a stop of the predetermined block after exchanging the tool; and a state restoration executing unit that, in a case in which the internal state is confirmed to be restorable, restores the internal state to a state at the time of exchanging the tool based on the stored operating condition of the program at the time of exchanging the tool.

An electrically-adjustable tool holder precisely movable in a straight line within a magnetic field under electrical stimulation includes a handle body, a connecting member, and a driving member. The connecting member has a first end securely coupled to an end of the handle body, a second end opposite to the first end, and defines a through hole passing through the first end and the second end. The driving member includes a magnet securely received in the through hole, and an electrical electric coil movably received in the magnet. The electric coil is configured to be securely coupled to the tool, and moves the tool up or down along the central axis of the handle body.

A processing device includes a mounting base, a cutter holder, and a brake. The brake includes a driving member, a resisting member, and an elastic member. The driving member includes a main body and a driving shaft movably placed in the main body. The driving shaft is driven to move in a straight line by the main body. One end of the driving shaft is movably coupled to the cutter holder, and another end of the driving shaft is coupled to the resisting member. The elastic member is positioned between the main body and the resisting member. The driving shaft is configured to move toward one side of the driving member adjacent to the elastic member under an elastic restoring force of the elastic member, whereby the cutter holder moves with the driving shaft toward one end of the driving member adjacent to the elastic member.

A method of installing a push-in fastener includes the steps homing a floating tool assembly to a home position, the floating tool assembly carries a locating pin and a punch, releasing the floating tool assembly, positioning a workpiece at a target position, retrieving a fastener with the punch, engaging the workpiece with the locating pin which causes the floating tool assembly to move to a desired working position with respect to the workpiece, locking the floating tool assembly in the desired working position, retracting the locating pin, and advancing the punch to install the fastener in the workpiece.
