A light barrier system is formed by the light transmitter portion and the light receiver portion, each being associated with a leg of an essentially U-shaped support structure of the measuring device. A fluid blowing device, associated with the measuring device, is provided for cleaning a tool to be measured, and/or a sealing air feed is provided in the area of a measuring beam of the measuring device designed as a light barrier measuring system, and/or a protective/closing device is provided at the light transmitter portion and/or the light receiver portion of the measuring device designed as a light barrier measuring system.

A method for checking a tool uses a device with a light emitter for beam emission for tool scanning and with a beam receiver for beam reception and for outputting a shadow signal; and an evaluation unit for processing the shadow signal; rotation of the tool; moving the tool until it reaches a starting position in which the blade dips into the beam and shades this such that a threshold of a range of the evaluation unit is reached or undershot; moving the tool, starting from the starting position, out of the beam and registering the shadow signal; ascertaining that the shadow signal for a cutting edge does not fall below the lower switching threshold or exceed the upper switching threshold such that a shadow signal lies above the lower and below the upper switching threshold; wherein the feed is determined in proportion to a measurement range.

An intellectual automatic tool changer (ATC) speed moderating system, which is disposed between a tool magazine and a tool exchanging arm, includes an image capture device for capturing the image of tools, and a processing device connected with the image capturing device. The processing device includes a receiving module for receiving the images of tools, a calculating module for calculating an assessment value of a tool according to the image of the tool, and a signal transmitting module connected with a controller of the tool exchanging arm for transmitting the assessment value of the tool to the controller. Therefore, the tool changing speed of the tool changing arm is controlled and moderated.

A laser projection method including the steps of: irradiating, from a laser projection unit, a workpiece that is a measurement object, with a laser while controlling a plurality of mirror angles; imaging the workpiece with a stereo camera, extracting a contour of the workpiece, and calculating a three-dimensional coordinate; calculating a positional relationship between the laser projection unit and the workpiece by comparing the calculated three-dimensional coordinate of the workpiece contour with the minor angle; and performing coordinate transformation of CAD data information and drawing CAD data from the laser projection unit to the workpiece, based on the positional relationship between the laser projection unit and the workpiece. The machining method including the steps of: selecting a component of a tool; assembling the component; imaging the tool assembled; and determining whether or not a desired tool has been assembled.

A measuring sleeve for measuring a tool, a tool presetting device, a method for measuring a tool by means of a tool presetting device and to a method for mounting a tool in a tool holder. The measuring sleeve for measuring a tool provides a base body, particularly in the form of a sleeve, with a recess which runs starting from a first end side of the measuring sleeve in the axial direction of the measuring sleeve and has cross sections, in particular circular cross sections, decreasing in steps for receiving a tool to be measured.

This machine tool has a tool changing device, and sequentially changes tools to machine a workpiece. The machine tool comprises: an input unit which receives a machining program output from a CAM system and tool basic data; a storage unit which stores the tool basic data received from the input unit for each tool number; a tool measuring device which measures the size of a tool loaded into a tool magazine of the tool changing device; and a determination unit which compares the tool basic data stored in the storage unit and the actual data measured by the measuring device, and determines that the measured tool is different from a desired tool if the difference between the two tool sizes is beyond a preset allowable range.

This tool exchange device for a machine tool uses an exchange arm to exchange tools between a processing area and a tool accommodation area which are partitioned by a partition wall provided with an opening and a shutter capable of opening and closing the opening. In the tool exchange device, an imaging device is used to capture an image of a tool in the tool accommodation area, the length of the tool is calculated from the captured image of the tool, the opening width of the shutter is determined in accordance with the length of the tool, and the shutter is opened to the determined opening width.
