A balance and runout amount adjustment system for a rotary tool includes a rotary tool constituted of a tool holder mounted on a spindle, a balance determining device configured to obtain outer circumference position data of the rotary tool and to determine a mass balance of the rotary tool based on the outer circumference position data obtained, in the course of rotation of the rotary tool and a runout determining device configured to obtain shape data of the rotary tool and to determine a runout amount of the rotary tool based on the shape data obtained, in the course of rotation of the rotary tool. The rotary tool is configured to be capable of adjustment of the mass balance based on the result of the determination made by the balance determining device and capable also of adjustment of the runout amount based on the result of the determination made by the runout determining device.

A machine tool includes a spindle device; a shutter which is disposed between a tool magazine disposed over a machining chamber and the machining chamber, and is capable of opening and closing; a tool exchange device; and a tool breakage detecting device to detect whether a tool indexed to a tool detecting position of the tool magazine has breakage or not, and performs a return step of returning a first tool to the tool magazine with use of the tool exchange device; an attachment step of attaching a second tool to the spindle device; and a breakage detecting step of rotatively moving the first tool returned to the tool magazine to the tool detecting position and detecting breakage of the first tool with use of the tool breakage detecting device, after the shutter is closed. This constitution can prevent erroneous detection and improve the operational efficiency of the machine tool.

A tool identification chip for an unambiguous marking of tools and/or tool holders is proposed, with a plate-like base body which has an adhesive side and a lettering side situated opposite the adhesive side.

An on-machine monitoring system for the failure state of the rotating tool and a detection method thereof are provided. The monitoring system includes a detector, a data processing controller, a tool data server, and a Hall current sensor. A tool diameter and a tool length are determined according to image sequences of a tool. A wear state and a breakage state of the tool are determined according to the tool diameter and the tool length. A spindle current signal is acquired by the Hall current sensor. And an edge chipping state and a breaking state of the tool are determined according to the spindle current signal.

A turning tool according to the present invention includes a tool main body that extends along a tool axis (J) and that has a base at a tip portion on one side in an axial direction (Dj) along the tool axis (J), a cutting insert detachably attached to the base, and a camera provided in the tool main body and configured to image a machined surface of a work material cut by the cutting insert, in which the camera is disposed to image an outer side in a radial direction (Dr) of the tool main body intersecting with the axial direction (Dj).

A method comprises at least one tool presetting and/or tool measuring apparatus for presetting and/or measuring tools in tool chucks or comprises at least one tool clamping device for clamping or unclamping tools in or from tool chucks, wherein, in at least one capturing step, one or more objects are captured in a field of view of a camera of the tool presetting and/or tool measuring apparatus or of the tool clamping device, and wherein, in at least one object recognition step, an image recognition algorithm is applied to camera images of the camera comprising the object/objects, wherein the object recognition step is specifically configured at least for application to objects mentioned in the following list: tool, tool chuck, tool cutting edge, mounted complete tool, tool and/or tool chuck pallet.

A protection member for an optical measurement device, such as a break-beam tool setting device for a machine tool. The protection member includes a conduit through which light and air can pass. The conduit is configured such that, in use, a beam of light is passed through the conduit along an optical axis and a stream of air is guided out of the conduit along an airflow axis. The optical axis is non-parallel to the airflow axis and the conduit has a varying cross-sectional profile along the airflow axis. Improved measurement repeatability is provided.

An image processing device includes: an imaging execution unit that captures a first partial image including a part of a tool by a camera, a position specifying unit that specifies a next imaging position on the basis of a partial shape of the tool included in the first partial image, and a position control unit that changes the relative positions of the tool and the camera to the specified imaging position. The imaging execution unit captures a second partial image including a part of the tool at the next imaging position.
