A system and method for monitoring and predicting wear of a cutting tool used for machining a workpiece is disclosed. The system includes a cutting tool having a shank and a cutting head. The system also includes a split, modular and wireless wear detection system including one or more sensors mounted to the cutting tool for providing a data signal representative of a physical condition of the system, and a data recording and data transmitting device for recording the data signal from the one or more sensors and for generating and transmitting a data signal to a processor. The processor applies a machine learning data processing technique in real time to monitor and/or predict a condition of various components and/or parameters of the system during a metal cutting operation.

The invention relates to a tool post of a machine tool, which tool post is capable of receiving a cutting insert for machining a component, characterised in that it comprises at least one sensor capable of determining a parameter representative of a cutting action between a component to be machined and a cutting insert, and a support housing (9) which is electrically connected to the sensor and comprises a battery (17) and a printed circuit board (19) supplied with current by said battery (17), wherein said printed circuit board (19) supports, at least partially, a radio transmission unit (11) and the housing (9) consists of a base (21) and a cover (23) which can be detached from one another, and in that the battery (17) is supported by the cover (23) and the printed circuit board (19) by the base (21) or vice versa.

A machine tool (1) includes: a front spindle (10) having a front chuck (12); a rear spindle (20) having a rear chuck (22); a controller (50) configured to cause the rear chuck (22) to perform a fastening operation for fastening a work (W) fastened to the front chuck (12) to the rear chuck (22); and a detector (60) configured to detect an abnormality caused by the fastening operation by the rear chuck (22), based on measurement data associated with a vibration of at least one of the front chuck (12) and the rear chuck (22).

A holder may include a base, an antenna and a sensor. The base has a bar shape extended along a central axis from a first end toward a second end. The base may include a metal member and a first resin. The metal member may include a pocket that is attachable of an insert including a cutting edge. The first resin may be located closer to the second end than the metal member. The antenna may be covered with the first resin. The sensor may be located closer to the pocket than the antenna and may be wired connected to the antenna, and may be measurable a state of the base. This configuration may contribute to solving the problem that handling of wiring becomes complicated.

A cutting tool may include a base body, a tip, a sensor, and a cover. The base body may have a shank portion extending in a first direction, a fixation portion, and a recess opening at an outside surface of the shank portion. The tip may be fixed to the fixation portion and may have a cutting edge. The sensor may be positioned inside the recess. The cover may close the recess. Among peripheral surfaces of the shank portion, a first area may face one side in a second direction that is a direction orthogonal to the first direction, and the cutting edge may be positioned further toward the one side in the second direction from the first area. The entirety of the cover may be positioned further toward the other side in the second direction from the cutting edge.

The present invention relates to a device for generating an ultrasonic vibration of a tool used for the ultrasonic machining of a workpiece and for measuring ultrasonic vibration parameters of the ultrasonic vibration of the tool having a tool holder for receiving the tool, an ultrasonic transducer in the tool holder for generating the ultrasonic vibration of the tool, a sensor mechanism in the tool holder for producing a sensor signal on the basis of the ultrasonic vibration of the tool, and a sensor signal evaluation device for evaluating the sensor signal.

Auxiliary handle installed on the casing (11) of a drill (1) having a drilling axis (Xo), incorporating an electronic acceleration meter (231), with axes (XoYoZo) defining a reference point; one (Xo) of the axes being the drilling axis; the other axis (Yo) being that of the handle (2); and a reference surface (SR, SR1-SR3, 3, 4) associated with the reference point of the acceleration meter (231) to register the relative position between the surface to be drilled (S) and the drill (1), and calculate the set position of the drilling axis (Xo), and a display (25) to show the set position of the handle (2) calculated from the set position of the drilling axis (Xo) to execute the drilling.
