A system and a method for machine tool maintenance and repair is provided for allowing an expert at a remote site to collaborate with an on-site personnel to maintain or repair a physical machine in a manner of combining the physical machine with a virtual reality (VR) model or an augmented reality (AR) model. Two maintenance modes are provided, which are an augmented virtual reality model guided by a standard operation procedure (referred as a SOP-AVR mode), and an augmented virtual reality model guided by an expert operation procedure (referred as an EG-AVR mode). A cyber physical agent (CPA) is adopted for simultaneously monitoring and repairing plural machines of the same machine type.

An automated constructing method of cloud manufacturing service is provided for a distributed system including a virtual machine and a service manager. The method includes: obtaining a library package which is locally built, analyzing the library package to obtain key information, and generating a library information file; automatically generating a project source code file according to the library information file, and generating a web service package according to the project source code file; and deploying, by the service manager, the web service package on the virtual machine.

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.

The present invention relates to a method and a device for controlling an ultrasound tool unit for machining a workpiece on a machine tool. For this, a plurality of parameter sets are stored on a storage device of a control device of the machine tool. When controlling an ultrasound transducer of the ultrasound tool unit received on a work spindle of the machine tool on the basis of a sensor signal input into a controller by means of a generator operated by the controller, on the basis of a first parameter set, which is associated with the ultrasound tool unit and sets the operation of the controller, an operating setting of the controller is switched by changing the first parameter set setting the operation of the controller on the basis of a second parameter set, which is associated with the ultrasound tool unit, of the plurality of parameter sets stored on the storage device.

Provided is a rotary machine tool with which it is possible to measure, in real time, the damage or extreme wear thereof. The rotary machine tool of the present invention is provided with at least: a sensor installation hole which has the rear end being open to the exterior at the rear end of the main body of the rotary cutting tool, and the tip being above the tip of the main body of the rotary machine tool and closed off from the exterior; a sensor that is positioned at the tip of the sensor installation hole and detects the state at the positioned position; and a sensor insertion hole that is connected to one end of the sensor and is coupled with the rear end of the rotary cutting tool.

A method is proposed for operating at least one hand-held power tool, in which a data processing device, realized separately from the hand-held power tool, processes at least one application quantity, in particular a vibration quantity, with respect to a user.

In a machine tool, when machining is in a steady zone, a rotation phase of a main spindle at the time of measurement in the N-th sampling is calculated, and the calculated rotation phase and the measurement value are recorded in a recording section so as to be associated with each other. The measurement and calculation of the rotation phase of the main spindle at the time of each measurement are continued for plural times of rotations of the main spindle, and thus the measurement values are obtained at various rotation phases, whereby change in drive force during one rotation of the main spindle is finally calculated.

An apparatus for detecting the status of a tool in a machine tool may include: a sensor unit configured to sense acceleration of a spindle of the machine tool in an x-axis direction and a y-axis direction during processing; and a processing device configured to convert the x-axis signal and the y-axis signal, sensed by the sensor unit, into signals capable of representing a cutting force by processing the x-axis and y-axis signals, detect a resultant force, and plot the detected resultant force on a polar coordinate system.

The invention relates to a handling device and method for monitoring a handling device having a holding device, in particular a vacuum gripping device or a vacuum tensioning device, for fixing a workpiece, and having a sensor device for detecting vibrations and for generating measured values therefrom. The sensor device is situated on the holding device and is configured for detecting vibrations of the workpiece that is fixed to the holding device.

An information measuring device includes a sensor that obtains information on a phenomenon periodically occurring on an apparatus while being synchronized with the steady repetition of an operation and a control device. The control device associates the obtained information with an operation phase in the operation so as to generate change in the phenomenon in one cycle based on the information obtained during the operation of several times. Meanwhile, an operation cycle where the operation is repeated in the apparatus, a sampling cycle, and a duration where the operation is steadily repeated in the apparatus are included in measurement parameters. The control device calculates an optimum measurement parameter from a relation between the measurement parameters on at least one of the measurement parameters and changes the measurement parameter as a target to the optimum measurement parameter.
