A tool holder having at least one sensor and a transmission device for transmitting the data captured by the sensor to a higher-level controller. The power supply to the sensor or the data module can be interrupted without contact when the tool holder is removed from the machining space of a machine tool. This prevents, for example, the power supply from being discharged while the tool holder is in a magazine outside the machine, and, for example, significantly increases the availability and service life of the tool holder before a battery is replaced, and/or before the accumulator and/or charge storage device is recharged.

A workpiece and cutter pose calibration method based on robotic edge milling error tracking, including: 1. generating an edge milling trajectory point cloud; 2. obtaining an actual edge milling three-dimensional point cloud; 3. generating an updated edge milling three-dimensional point cloud; 4. calculating an edge milling allowance error and a posture inclination error; 5. solving position errors of the workpiece and cutter; 6. solving posture errors of the workpiece and cutter; 7. updating pose parameters of the workpiece and cutter; 8. repeating steps 4 to 7 until pose error vectors of the workpiece and cutter are both not greater than corresponding preset thresholds. The disclosure performs error comparison, error modeling, and error tracking on the three-dimensional point cloud and edge milling trajectory point cloud, even if the cutter has system errors such as axis deviation, the disclosure can accurately identify pose errors of the workpiece and cutter during edge milling.

A method is provided for monitoring a milling method for a milling machine provided with a milling tool comprising cutting teeth, the method including: determining measured values of a first parameter corresponding to a bending of the milling tool as a function of a second parameter corresponding to an angle of rotation of the milling tool in a rotating frame of reference of the milling tool and analyzing the measured values as a function of at least one monitoring criterion.

When machining small diameter holes, tool breakage and torque fluctuation at the machining point are detected. The machining method includes: measuring a reference thrust of a spindle when the spindle is fed from a machining feed start point to a machining end point in a direction in which the spindle extends under a machining condition without machining a workpiece; determining a threshold with respect to a feed coordinate based on the reference thrust; measuring a machining thrust of the spindle with respect to the feed coordinate while machining the workpiece; and comparing the machining thrust with the threshold with respect to the feed coordinate.

A system to control a workpiece during its manufacturing in a machining system. The control being performed in the same manufacturing phase following machining operation. The workpiece being set in the work volume of the machining system. The check operation includes the acquisition of points on the surface of the part. The robot is moved by a cart so the robot can reach the protected working area. The measuring device is positioned relative to the workpiece by the robot. Acquisition of a plurality of points on the surface of the workpiece is performed. The position of the plurality points acquired is compared with the three-dimensional model stored in the memory of the computer.

Provided is a method for evaluating tool installation when fastening a tool to a main shaft of a machine tool, wherein the method includes a storage step for storing a reference location of a draw bar at the time when the tool is contacting a mounting seat of the main shaft, in a state in which foreign matter has been removed from the surface of the mounting seat and from the contacting surface of the tool. The method for evaluating tool installation includes a measuring step for measuring a measurement location of the draw bar when the tool is installed on the main shaft, and a determination step for determining the installation state of the tool to be abnormal if a measurement-location error with respect to the reference location exceeds a predetermined determination range.

A router power tool including a housing mounted to be moveable with respect to and spaced from a base, said housing including a motor to rotate a shaft which includes, at its free end, a tool holder for a cutting tool, said shaft extending from the housing such that the tool holder is located at or adjacent to the base and said housing is connected to the base by at least one extendable assembly. The power tool is selectively locatable with a guide plate via retaining means. The guide plate includes apertures for the receipt of retaining means to allow the power tool to be engaged therewith and datum tabs to contact with the power tool to ensure the accurate location of the power tool with the guide plate when held in position by the retaining means.

A method to ascertain a quality of a product formed by a subtractive manufacturing device from a workpiece includes: determining a deflection/test force relation for a deflection of the device; measuring an actually exerted machining force applied by the device to the workpiece; automatically determining a machining force reference for the actually exerted machining force; automatically evaluating whether the actually exerted machining force deviates from the machining force reference. If an actually exerted machining force deviates from the machining force reference, then the method uses the deflection/test force relation to automatically determine for the actually exerted machining force, at least one correction deflection of the device and automatically creating at least one corrected drive control signal to fully or partially reduce the correction deflection.

A machining center having at least one door to control access to an enclosure thereof, where access through the door is provided by an unlocked latch, and the latch is unlocked based on wirelessly communicated signals relaying information about at least one operating condition of a fluid driven cutting tool spindle in use within the machining center.

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.
