A cutting tool, a turning machine including the cutting tool, and an associated method are provided. The cutting tool includes a tool bar extending along an axis, a cutting head located at the tool bar, and at least one sensor integrated with the tool bar or the cutting head. A rotational orientation of the cutting tool with respect to the axis is estimated based on output provided by the at least one sensor. In at least some embodiments, the at least one sensor includes accelerometers configured to measure acceleration in at least two directions.

An edge finder to locate a work piece, work-holding feature or cutting tool with respect to the spindle of a machine tool includes a shank, a body and an indicator. When the shank is attached to the machine tool spindle, the longitudinal axis is coextensive with the spindle axis of rotation. The indicator measures the location of a work piece, work-holding feature or cutting tool with respect to the shank longitudinal axis. The indicator is rotatable so that a machinist may read the indicator from any direction.

Instruments and methods for measuring and adjusting gate openings of a slicing machine utilizing a gauge system that includes a frame, a device for securing the frame to the interior surface of a cutting head, a device for locating the frame relative to a knife and/or a gate of the cutting head that define the gate opening therebetween, and a device mounted to the frame for measuring the gate opening. The measuring device includes an anvil biased in an outward direction relative to the frame, an indicator mounted to the anvil and biased therewith in the outward direction relative to the frame, and a probe of the indicator biased in the outward direction relative to the indicator. The probe and anvil provide a outward measurement of the gate opening based on a differential measurement of surfaces of the knife and gate.

A highly convenient machine tool system is provided. An NC lathe as an example of the machine tool system includes a first tool post to which a first tool for machining a workpiece is attached, a numerical control unit adapted to control a movement of the first tool post according to a numerical control program, and a scanner adapted to measure a position and a shape of the first tool attached to the first tool post brought to a predetermined position under control of the numerical control unit.

A set-up gauge for precision alignment of the cutting knives in a cutter head. The set-up gauge utilizes a support bar extending laterally across the wood shaper. Also included is a bracket slidably secured to the support bar and a rod extending outwardly from the bracket, the rod further comprising first end and second ends. Further included is a magnetic disc secured to the second end of the rod, the magnetic disc for contact with a surface of the cutting knives to identify a common inset distance for each of the cutting knives relative to the guide fence.

A method or device for monitoring a work spindle's tool clamping system of a numerically controlled machine tool with a control device controlling the processing of a workpiece with a tool clamped to the work spindle by a tool interface when a tool is clamped to the work spindle's tool interface holder by a tool interface, wherein the work spindle has a plurality of force sensors on a tool interface holder's bearing areas of the work spindle and force sensors' sensor values of the work spindle are provided on the control device with the tool clamped by means of the tool interface to the work spindle's tool interface holder, including monitoring the work spindle's tool clamping system when the tool is clamped by means of the tool interface to the work spindle's tool interface holder at the control device on the basis of a determined force distribution.

A cutting tool, a turning machine including the cutting tool, and an associated method are provided. The cutting tool includes a tool bar extending along an axis, a cutting head located at the tool bar, and at least one sensor integrated with the tool bar or the cutting head. A rotational orientation of the cutting tool with respect to the axis is estimated based on output provided by the at least one sensor. In at least some embodiments, the at least one sensor includes accelerometers configured to measure acceleration in at least two directions.

A motor-driven machine tool unit having a stator unit and at least one rotor unit having a rotor shaft that is rotatable about an axis of rotation. The rotor unit includes at least one first bearing unit arranged in the end region of a tool and/or workpiece receptacle, and a second bearing unit arranged at the opposite end region for mounting the rotor shaft in the stator unit. At least one electrical power transmission unit for transmitting electrical power between the stator unit and the rotor unit is provided. The problem addressed by the invention is that of better satisfying the increasing demands on modern machine tools or machine tool units. This problem is solved by the electrical power transmission unit is arranged in the end region opposite the tool and/or workpiece holder and/or on the second bearing unit.

A method and a device for adjusting a knife assembly of a knife ring to a predetermined knife projection, wherein the knife assembly is designed to be arranged in the knife ring at a chip angle , relative to the inside of the knife ring. The knife assembly is formed by a knife holding plate and a chipping knife which are positively connected with one another in a predetermined, relative target position. A knife assembly to be adjusted is provided, wherein the knife holding plate and the chipping knife are displaceable relative to one another. The knife holding plate is displaced in its plane, transversely to its direction of longitudinal extension towards its rear edge, against a first stop. The chipping knife is displaced in its plane against the stop surface of a second stop, until the predetermined knife projection has been reached.

A method of determining pull-out of a cutting tool mounted in a rotatable tool holder includes the steps of rotating the tool holder and thus the cutting tool, machining a work piece with the rotating cutting tool, measuring an axial position of the cutting tool in the tool holder during machining by a position sensor in the tool holder, calculating an axial displacement from an initial position of the cutting tool by the measured axial position, and determining pull-out of the cutting tool when the axial displacement exceeds a threshold value. A rotatable tool holder for a cutting tool, a machine tool system including a rotatable tool holder and use of the tool holder and machine tool system is also provided.
