摘要： A machine tool includes: a main spindle that holds a work piece; a tool holding unit that holds a tool for processing the work piece; a detection unit that detects vibration generated during processing of the work piece; and a processor that controls machining of the work piece performed by the tool, in which the processor compares a detected value detected by the detection unit with a predefined threshold value, interrupts the machining by releasing contact between the work piece and the tool at time of generation of chatter vibration or when there is a sign of the generation of the chatter vibration in which the detected value exceeds the threshold value, and analyzes the chatter vibration while the machining is being interrupted on basis of the detected value detected by the detection unit before the interruption.

摘要： A method and a device can measure machine error of an axis of rotation in a tool post having a touch probe without restriction of an angular range of an angle of rotation. Directions of a measurement plane and a measurement axis in a five-axis measurement are switched in correspondence to a range of the angle of rotation in a touch probe. The five-axis measurement is carried out by setting a position in a direction of a measurement axis in a measurement plane to a position where a reference sphere does not interfere with a lever rod of the touch probe as occasion demands. The five-axis measurement is carried out, for example, by setting the measurement plane to a position which is perpendicular to a line connecting an estimated center of the reference sphere and a center of a tip sphere or the lever rod of the touch probe.

摘要： A first speed and a second speed slower than the first speed are set as a contact speed when a work w and a detection jig t attached to a tool post are brought into contact with each other to detect a position or a posture of the work w, the work and the detection jig are brought into contact with each other at the first speed, the detection jig and the work contacting each other are separated from each other by a predetermined distance, the work and the detection jig which are separated from each other are brought into contact with each other at the same position at the second speed, and a correction value δ is obtained based on a tool post position or a spindle angle during the second contact.

摘要： A dividing device divides a wafer from an ingot by slicing the ingot by using a dividing layer which is formed by relatively moving a laser beam to a predetermined depth of the ingot from one of both end faces of the ingot. The dividing device for a wafer includes: first fixing part that fixes the other of the both end faces of the ingot; second fixing part that is arranged on a first central axis line of the ingot so as to face the first fixing part and fixes the one of the both end faces of the ingot; and tension part that apply a tensile force to the ingot via the first and second fixing parts. The tension part rotates one end of the dividing layer with another end as a fulcrum so as to generate moments for slicing the ingot with the dividing layer as a boundary.

摘要： A processing head of a laser cladding apparatus, configured to form a cladding layer on a substrate, includes: a laser irradiation part that introduces incident laser light and irradiates the substrate with the laser light; a jet nozzle, into which an assist gas is introduced and which forms a jet of the assist gas around the laser light; and a powder storage part that stores a cladding material powder to be fed to the substrate. The powder storage part has a powder feeding port that is opened facing a jet formation region of the assist gas.

摘要： The invention relates to a device controlling a chuck of a machine tool and an auxiliary equipment thereof, thereby facilitating a setup work. Gripping and releasing of a work are confirmed by registering a work gripping position and a work releasing position of a chuck, a kind of a used chuck, and a gripping direction of a work in an external memory device every product type of the work, transferring the work gripping position and the work releasing position in correspondence to the product type to a controller of a machine tool displaying them on a display of an operator control panel, detecting a position of an operation rod opening and closing a claw of the chuck by a stroke sensor, referring to the gripping position of the work, and detecting conformity of the detecting position and set values of the work gripping position and the work releasing position.
