A numerical controller performs control to rotate a turret, which holds a plurality of tools on the outer peripheral portion thereof, thereby moving one (selected tool) of the tools selected by a command to a predetermined position (selected position). The numerical controller sets and holds a partial area of the outer peripheral portion of the turret as an area (passage-prohibited area) prohibited from passing through the selected position and determines whether or not the selected tool is present in the passage-prohibited area or whether or not the passage-prohibited area passes through the selected position as the selected tool is moved to the selected position.

A power/signal transmission structure includes: a movable body which has an electrical device, and at least a part of which moves in a processing chamber of a machine tool; a robot provided in the processing chamber; a first connector which relays at least one of power and signals, and which is provided in the movable body 48 and is electrically connected to the electrical device; and a second connector which relays at least one of power and signals, and which is provided in the robot, and is electrically connectable to and disconnectable from the first connector as the robot is driven, wherein at least one of power and signals is transmitted from outside to inside or from inside to outside of the electrical device through the first connector and the second connector.

The controller for a machine tool according to the present invention makes it possible to discharge both a coolant and an oil mist from a through hole provided in the tool equipped to a main axis of a machine tool, allows a processing program to instruct the discharge of either the coolant or the oil mist, and carries out such a control that a state where the above-described tool is detached from the main axis is maintained during a predetermined period of time at the time of replacing the tool, and at the same time, the oil mist is discharged from the above-described oil mist unit so as to remove the coolant from the above-described piping during the predetermined period of time.

A machine tool includes a display operation device, and a control device to display multiple individual operation buttons and a display switching button on the display operation device and execute control indicated by the multiple individual operation buttons and the display switching button in accordance with an operation performed on the multiple individual operation buttons and the display switching button. The multiple individual operation buttons are buttons to provide an instruction of a series of operations executed by the machine tool in multiple stages. The control device displays button information indicating the individual operation button in accordance with a state of the machine tool among the multiple individual operation buttons on the display switching button, switches the button information displayed on the display switching button in accordance with an operation of executing the display switching button, and switches the button information in order of the series of operations.

A packaging machine is disclosed that includes a deep-drawing station, a filling station, a sealing station, or a combination thereof. The deep-drawing station, the sealing station, or both have an upper tool including a supporting top part. The supporting top is pivotable via a pivot mechanism, and the pivot mechanism is detachable from the supporting top part.

3D modelling and robotic tool systems and methods are provided that enable more efficient spatial processing of an object and its surroundings. The robotic tool system comprises: a scanner, configured to capture spatial data of an object and its surroundings; a processor, configured to: allocate the spatial data to cells of a cellular space; determine one or more characteristics of a cell according to data of adjacent cells; and configure a robotic tool to operate on the object at least in part according to the one or more characteristics.

An object of the present invention is to provide, in a machine tool, a tool changer that can quickly investigate and recover a stop of a change arm when a failure occurs during a change operation of a tool post and the change arm stops. In order to accomplish the object, this invention provides a tool changer provided in a machine tool and including a change arm 5 that performs a tool change operation from a first tool 2 of a tool post 1 to a second tool 4 of a replacement tool holder 3, wherein when an abnormality is detected during the tool change operation from the first tool 2 to the second tool 4, the tool change operation that has been stopped is performed in reverse order to return the change arm 5 to a state before the abnormality detection.
