In the high-efficiency machining of blade parts according to the present invention, there is no reversal of the operating direction of a rotating shaft, and a high-quality machined surface can be obtained rapidly. A machining program is created for a workpiece such that: when a part having a convex curved surface and a concave curved surface, with a pair of edge portions as a boundary, is removal-machined, a virtual convex curve, the curvature of which is not inverted with respect to the convex curved surface, with the curves of the pair of edges as the tangent line, is set for the concave curved surface; a drive surface, for defining tool orientation without curvature inversion, is created by using the virtual convex curve, the convex curve set on the convex curved surface, and the convex curves set on the pair of edges; and a tool axis direction during removal machining is set on the basis of the normal direction of the drive surface for tool orientation definition.

A method for installation and/or maintenance of a flange connection includes screw connections with a manually movable tool including a screw tensioning structure, a processing unit and a screw identification sensor. The method includes assigning a one-to-one identification to each screw connection of the flange connection, determining a screw connection to be tensioned, positioning the tool on a respective screw connection to be tensioned, identifying the respective screw connection by the screw identification sensor, releasing the screw tensioning structure by the processing unit, and tensioning the respective screw connection by the screw tensioning structure. It is checked whether the tool or the screw tensioning structure is placed correctly on the screw connection. The screw tensioning structure is released when the result of this check is positive and/or the screw tensioning structure is blocked or stopped when the result of this check is negative.

A system and method for forming a structure with steep walls (walls having an angle greater than 60° with respect to a level plane) through one or more incremental sheet forming operations is provided. The method includes a workpiece with an inner region and an outer region that are separated by a boundary region. The boundary region includes a plurality of openings and a plurality of connecting elements. The openings are cut into the workpiece using a boundary region cutting tool. A forming tool is configured to operate on the inner region after the boundary region cutting operation has been completed. At least one control unit is in communication with the forming tool. The at least one control unit operates the forming tool to form the structure from the inner region.

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.

A wire electrical discharge machine acquires measured dimensions of a test workpiece that has been machined with a wire electrode inclined at a given angle with respect to a running direction in which the wire electrode runs; and calculates, based on the measured dimensions, first actual information indicating an actual holding position at which the wire electrode is actually held at a first die guide for guiding the wire electrode to a workpiece, and second actual information indicating an actual holding position at which the wire electrode is actually held at a second die guide for guiding the wire electrode sent from the workpiece, and, when necessary, the wire electrical discharge machine rewrites first information and second information stored in a storage unit to the calculated first actual information and second actual information.

The control device includes a brazing controller configured to control a brazing material moving mechanism so as to retract a tip of a brazing material from a heating position to interrupt the brazing, during execution of the brazing, and a movement controller configured to, when the brazing is interrupted, control a movement machine so as to retract a heating device or a base material in a direction opposite to a movement direction during the execution of the brazing, and subsequently advance the heating device or the base material in the movement direction again. The brazing controller resumes the brazing by controlling the brazing material moving mechanism so as to cause the tip of the brazing material to reach the heating position at the same time when the heating device or the base material advanced by the movement controller reaches an interruption position at which the brazing is interrupted.
