In a method for determining the state of wear of a tool, at least one optical image of a surface of the tool is recorded. Image data of the at least one optical image are processed in order to detect a wear zone. A surface extent and/or spatial extent of the wear zone is determined. The state of wear of the tool is classified on the basis of the extent determined. An apparatus for determining the state of wear of a tool correspondingly comprises a camera for recording at least one optical image of a surface of the tool, an image processing module which is configured in such a way that it processes image data of the at least one optical image in order to detect a wear zone, a computation module which is configured in such a way that it determines a surface extent and/or spatial extent of the wear zone, and a classifier module which is configured in such a way that it classifies the state of wear of the tool on the basis of the extent determined.

According to the invention, the measuring means (20) are mounted directly at the guide means.

A machine tool includes: a tool magazine that stores a plurality of tools; a spindle that holds one of the plurality of tools stored in the tool magazine; a glossiness measurement unit that measures glossiness of a tapered outer surface of a taper shank of each of the plurality of tools; a deterioration determination unit that determines whether or not the tapered outer surface is deteriorated on the basis of the glossiness measured by the glossiness measurement unit; and a notification unit that notifies an operator of deterioration of the tapered outer surface if it is determined by the deterioration determination unit that the tapered outer surface is deteriorated.

A forming tool detection device includes a reflector module, an image sensor and a backlight module respectively disposed on both sides of the reflector module with a detection space formed between the backlight module and the reflector module for the insertion of a forming tool for detection. The reflector module focuses the light projected by the backlight module and reflects the focused light toward the backlight module and is provided with a hollow portion for the image sensor to capture an image of the forming tool. The reflector module is used to reflect the light emitted by the backlight module so that the tool image captured by the image sensor can detect the length and outer diameter of the forming tool, thereby simplifying the tool detection process.

A machine tool includes a camera fixed to a predetermined imaging area and for imaging a tool inserted into the imaging area, a tool holding portion to which a tool is attachable, and a machining control portion for controlling the tool holding portion in accordance with a machining program and machining a workpiece with the tool. The machining control portion moves the tool toward the imaging area after rotating the tool to image the tool.

A method for determining a dimension between the back and the cutting edge of a vibrating blade mounted on a cutting head includes successively of acquiring a digital image of the blade mounted on the cutting tool so a line corresponding to a cutting edge of the blade and a line corresponding to a back of the blade are visible in the image, determining on the digital image along a straight line perpendicular to the line corresponding to the cutting edge of the blade the pixels comprised between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade, and calculating a filtered dimension between the back and the cutting edge of the blade from the number of pixels comprised between the line corresponding to the cutting edge of the blade and the line corresponding to the back of the blade.

Grinding and/or erosion machine (10) for machining a chip-cutting rotary tool including a tool body (18) and several cutting plates (19) per existing pitch (TR). A control device (25) activates an axis arrangement (11) to move a machine tool (12) and the rotary tool (13) to be machined relative to each other. An interface device (26) triggers a data import function for reading-in the position data of the cutting plates (19). The position data (P) describe at least one angular value (1, 2), a first length value (z1) and a second length value (z2). The control device (25) imports the position data (P) in chaotic order and allocates the position data (P) of each cutting plate (19) in the imported machine data set (M) to respectively one separate virtual pitch (TV), independent of whether the cutting plates (19) belong to a common pitch of the rotary tool (13).

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.

An apparatus for provisioning, in particular automatically, a complete tool having a toolholder and a tool, in particular a drilling and/or milling tool. The apparatus has a spindle that can be driven in rotation by a driving device. The spindle has a holding device for holding a toolholder. A measuring device, in particular an optical measuring device, measures a complete tool, held on the spindle. A heating device in the region of the spindle heats a shrink-fit chuck of the toolholder held on the spindle. A cooling device, in particular a cooling device associated with the spindle, enables the spindle and/or the complete tool held on the spindle, to be cooled.

A multi-clamping and measuring and/or presetting station for tools is configured for an automated, preferably fully automated, mounting of tools into tool holders and/or demounting of tools from tool holders and for an adjustment, in particular at least a length adjustment, and/or measuring of the tools in the tool holders with at least two, in particular fully automated, tool clamping-in units, with at least one, in particular optical, measuring and/or presetting apparatus for tools and with at least one handling robot, which is at least configured to move tools and tool holders between the tool clamping-in units and the measuring and/or presetting apparatus.
