A workpiece processing method includes: a section roll forming step of subjecting a flat plate shaped workpiece to forming to impart a prescribed cross-sectional shape thereto; a solution heat treatment step of subjecting the workpiece, after the section roll forming step has been performed, to solution heat treatment; a contour roll forming step of subjecting the workpiece, after the solution heat treatment step has been performed, to forming to bend the workpiece into an arcuate shape; and a stretch forming step of subjecting the workpiece, after the contour roll forming step has been performed, to forming to impart a curved shape, following a curved surface of a die, to the workpiece by bringing the workpiece into contact with the curved surface and inputting a tension load to the workpiece.

Workpiece processing method and processing device

An inspection system for a fabricated object formed by layering powder includes an acquisition unit that acquires an image of a surface of each of layers, an identification unit that identifies a defect portion (protruding portion or recessed portion) on the surface of the powder and a position of the defect portion based on the acquired image, and a determination unit that determines that an abnormality occurs when the defect portion successively occurs at a same position in the plurality of layers.

Inspection system, inspection method, and inspection program

To provide a robot control system and a robot control method capable of placing a component grasped by a robot hand at an accurate location on another member. A robot control system is provided with: a robot hand configured to grasp a clip; a camera configured to capture an image of the clip grasped by the robot hand, a calculation unit configured to calculate a position of the clip or an inclination of a component based on an imaging result of the clip captured by the camera, and a robot control unit configured to control the robot hand to adjust, based on the position of the clip or the inclination of the component calculated by the calculation unit, a position or an inclination of the robot hand and move the clip to a stringer.

Robot control system and robot control method

A processing device processes a frame-shaped workpiece which extends in a prescribed extension direction, and includes, integrally, a plate-shaped web surface portion, a plate-shaped first flange portion that bends and extends from one end of the web surface portion, and a plate-shaped second flange portion which bends from the other end of the web surface portion and extends in the opposite direction to the first flange portion. The processing device includes a shaping device which conveys the workpiece in the extension direction, and an exit side pinch roll device provided further downstream, in the workpiece conveying flow direction, than the shaping device. The exit side pinch roll device includes a first roll which presses a central region of an upper surface side of the web surface portion, and a second roll which presses a central region of a lower surface side of the web surface portion.

Processing device, and method for controlling processing device

Visibility of relevance of detailed configurations is improved while deterioration of the visibility of a general configuration between nodes is suppressed. A node coordinate calculation process calculates, upon calculation of deployment coordinates of each node, a degree of importance of an infrastructure resource and a degree of importance of an application, and weights the distance between the application node and the infrastructure node with the reciprocal of the degree of importance of the infrastructure node. Then, the node coordinate calculation process determines deployment of the application node such that the application node is deployed in the proximity of a comparatively important infrastructure node, and determines deployment of the application node on the basis of the degrees of importance of the applications such that a comparatively important application is deployed closely to the infrastructure node.

Display information processing apparatus, display information processing method and computer readable recording medium

The present invention provides a method for fabricating a metal matrix composite having high specific strength and stable performance and capable of fabricating at low cost, the method comprising heating a preform of metal matrix with reinforcing fiber to the temperature, which is below the high temperature region, of low temperature region or medium temperature region of the plastic deformation temperature of the metal matrix in a pressure vessel having an initial processing pressure and keeping for a predetermined time for a preparative treatment before the step of hot-isostatic-pressing the preform by keeping at a high temperature region capable of HIP treatment and of diffusing welding temperature of the metal matrix in a pressure vessel; for instance, in case metal matrix is titan or titan alloy, the preparative treatment is conducted at a preparative treatment temperature of about 300&#xb0; C. to 700&#xb0; C. and at a pressure in the pressure vessel of about 30 to 100 kg/cm.

Method for fabricating metal matrix composite

The present invention provides a metal matrix composite having stable performance without extremely weak portions and capable of assuring strength with a simple structure, the metal matrix composite being formed by hot-pressing or hot-isostatic-pressing a flat formation of reinforcing fibers sandwiched between metal matrices and comprising a joined end part in the longitudinal direction of reinforcing fibers which is joined obliquely at a joining angle of 5 to 60 degrees with respect to the longitudinal direction of reinforcing fibers or more preferably wherein a plurality of metal matrices and a plurality flat formations of reinforcing fibers are lapped each other to form layers of metal matrices and flat formations of reinforcing fibers so that the adjacent upper layers of flat formations of reinforcing fibers and the adjacent lower layers of flat formations of reinforcing fibers to a layer having a joined part of flat formations of reinforcing fibers are continuous and have no joined parts.
