A processing method includes: a step of setting a workpiece having a workpiece surface made of a material containing metal, on a precision processing machine; and a forming step of forming multiple grooves having a V-shaped cross-section, at intervals of a constant pitch in a predetermined area on the workpiece surface, using a tool provided in the precision processing machine to thereby form a V-groove pattern made up of the multiple grooves, in the predetermined area. In the forming step, each time one groove is formed, the relative position between the tool and the workpiece is moved in a direction intersecting the longitudinal direction of the groove and the angle of the groove face of the groove is gradually varied so that a uniform color can be visually recognized in every location in the predetermined area when the predetermined area is observed from a predetermined viewpoint.

The detection system includes a height measurement sensor which measures height of a moving workpiece, a two-dimensional sensor which acquires two-dimensional information of the workpiece, an execution management section which manages execution timing of at least one of the height measurement sensor and the two-dimensional sensor, and a workpiece detection section which detects at least a position of the workpiece based on the measured height and the acquired two-dimensional information.

Disclosed are an automatic attachment changer and a boring machine having the same. The automatic attachment changer includes a stacker in which a plurality of attachments is stacked in a height direction by a unit of housing cell having a length larger than the attachments such that the attachment is individually arranged in each housing cell horizontally with respect to a bottom of the stacker, a stacker carrier having a carrier body secured to the stacker, a body transfer transferring the carrier body and a carrier power driving the body transfer, and an attachment changer controlling the stacker and the stacker carrier such that a select attachment is selected among the attachments and the select attachment is combined to a spindle assembly. The attachment is changed in the boring machine with high reliability and correctness.

A balance and runout amount adjustment system for a rotary tool includes a rotary tool constituted of a tool holder mounted on a spindle, a balance determining device configured to obtain outer circumference position data of the rotary tool and to determine a mass balance of the rotary tool based on the outer circumference position data obtained, in the course of rotation of the rotary tool and a runout determining device configured to obtain shape data of the rotary tool and to determine a runout amount of the rotary tool based on the shape data obtained, in the course of rotation of the rotary tool. The rotary tool is configured to be capable of adjustment of the mass balance based on the result of the determination made by the balance determining device and capable also of adjustment of the runout amount based on the result of the determination made by the runout determining device.

A hand-held tool system comprises a hand-held tool and a positioning device matching the hand-held tool. The hand-held tool comprises an output shaft and a working head coupled to the output shaft. The positioning device comprises a detecting module configured to detect a positional feature and/or a movement feature of the positioning device and output a parameter indicative of the positional feature and/or the movement feature, the detecting module and the working head having a preset distance therebetween; a storage module configured at least to record reference position information about the working head; a control module configured to acquire real-time position information about the working head based on the parameter, the preset distance and the reference position information; and an output module configured to output the real-time position information in a way that can be perceived.

Methods and devices for controlling a mechanical joining or forming process, in particular friction drilling in thin-walled materials, apply several reverse pulses acting on a process parameter to bring the course of an actual curve of the parameter more into line with the course of a predetermined nominal curve of the process parameter. The number and length of the reverse pulses and the length of the intervals between the pulses are determined as a function of at least one immediately detectable variable associated with the process parameter.

A power tool is provided. The tool has a housing containing an internal drive system that drives an output member that engages a workpiece and exerts mechanical force thereupon. A force sensor and a positional sensor are operatively connected to the drive system to sense characteristic variables of the drive system during engagement of the workpiece. A light unit is positioned on a front end and a top portion of the housing so as to be able to direct light of various colors onto the workpiece. A control unit is operatively connected to the drive system and the light unit so as to control the light unit based on the characteristic variables of the drive system measured by the sensors. The light unit may illuminate a colored light on the workpiece depending on whether or not the workpiece was determined to be fastened according to predetermined specifications.

A method of monitoring a tool clamping device mounted on a machine spindle, the clamping force of which tool clamping device is generated by a spring assembly which exerts a force in the direction of the clamping position on an actuating element actuating the clamping or the release of a tool or tool holder. In the method, the spring force and the displacement of the actuating element are continuously measured during the release and/or clamping of a tool or tool holder and recorded as functions of the time. These recorded functions are used to identify at least one parameter characteristic for the status of the tool clamping device. Based on the spring force and the displacement over time, a spring characteristic curve is plotted in the form of the spring force as a function of displacement, the analysis of which spring characteristic curve provides information about a number of characteristic parameters.

A machine tool system is equipped with a machine tool and a controller. The machine tool is equipped with a machine tool body and at least one temperature sensor that acquires temperature data of the machine tool body. The controller is equipped with a storage that stores the temperature data acquired in time-series by the temperature sensor, and an auxiliary power supply that supplies power to the temperature sensor and the storage when the supply of power to the machine tool body is stopped. The controller controls the machine tool by using the temperature data over a predetermined time range stored in the storage, and selects, in response to a charge state of the auxiliary power supply, the temperature data to be used in first control after the supply of power to the machine tool body is resumed.
