摘要： PROBLEM TO BE SOLVED: To improve the working efficiency by grindingly repairing linear flaws after completing the grinding repair of all the scattered flaws based on information obtained by processing taken pictures. SOLUTION: A mobile flaw removal device 1 crawlingly advances while searching flaw marks A41, B42 from an edge of a steel plate T and a start end of the steel plate T by an image processing, automatically climbs up on the plate, and searches the flaw marks A41, B42 on the steel plate T while moving in parallel to the longitudinal direction of the steel plate T. Where there are a plurality of flaw marks A41 in the visual field of an image recognition, the moving order to the flaw marks is decided taking account of the dispersion direction of the grinding chip, and the mobile flaw removal device 1 is moved to the flaw mark A41(δ) at high speed according to the order so as to repair the grinding. After completing grinding repair of the whole scattered flaws, the correlation of recognized flaw marks B42 group is analyzed, work planning for a moving path of the mobile carrier 2 and the grinding repair is drawn, and the grinding repair action of the linear flaws is executed in order.

摘要： PROBLEM TO BE SOLVED: To prevent useless chamfer states from being formed in edges by changing over the grinding depth control from presser force control or grinding power load control to grinding wheel position fixing control in grinding the edges. SOLUTION: A grinding wheel 51 is rotated from this side before a grinding start point (a) and moved along the X axis to the grinding start position (a). When the grinding wheel 51 reaches the grinding start position (a), the grinding wheel 51 is lowered, and when it reaches the grinding depth position (b), it is moved and ground along the X axis to an edge position (c). During moving from the point (b) to the point (c), the grinding wheel is controlled by the presser force control toward the thick board T to the grinding power load control. When the grinding wheel 51 approaches near the edge position (c) and an edge detector 61 detects the output change, the grinding wheel 51 is changed over from the presser force control or the grinding power load control to the grinding position fixing control so as to control the Z-axial position of the grinding wheel 51, thereby holding a prescribed position.

摘要： PURPOSE:To detect nozzle clogging from the change of measured values by moving a temp. sensor or pressure sensor just under the ejecting part of nozzle and in parallel with a group of nozzles and measuring the temp. or ejecting pressure of ejecting water or oil. CONSTITUTION:The temp. sensor 3 or a fixing table 4 on which the pressure sensor is fixed is moved just under the ejecting part of nozzle 2 and in parallel with this group of nozzles. Because the temp. or pressure of the ejecting part of nozzle is directly measured using the temp. sensor or pressure sensor, nozzle clogging can be surely detected. And the nozzle which clogging is generated can be specified by successively measuring each nozzle by moving the sensor. Then also the diagnosis of ejecting angle is possible by adjusting a locus on which the sensor is moved and a distance from the ejecting part.

摘要： PROBLEM TO BE SOLVED: To prevent a step difference from being formed in the circumferential edge in a grinding range by inclining a rotary axis by a specific angle relative to the moving direction of a grinding wheel and grinding in grindingly repairing flaws dispersed on the surface of a steel plate by a grinder. SOLUTION: A grinding wheel 51 is fed in the thick wall direction so as to have a prescribed grinding depth to grind while moving in the Y axial direction. The grinding wheel 51 is inclined by 45 deg. relative to the Y axial direction, or the longitudinal direction of a thick plate T, moved in the X axial direction by a prescribed pitch by which the grinding surface becomes flat, and reciprocatingly grinds in the Y axial direction. When the range N of the grinding repair includes the edge (c) of the thick plate T, the grinding wheel is fed in the thick wall direction so as to have a prescribed grinding depth and grinds while moving in the X axial direction, or the width direction of the thick plate T. In this case, the rotary axis direction of the grinding wheel 51 is made to incline by 45 deg. relative to the X axial direction, or the width direction of the thick plate T. This constitution enables shade grinding so as to provide a gentle curve whose grinding range boundary is decided by the curvature of the outer circumferential face of the grinding wheel.

摘要： PROBLEM TO BE SOLVED: To prevent a resin from sagging by making the length and cross section of the hole of an outlet die be in a relationship which satisfies a specified formula. SOLUTION: An outlet die 1 is attached to the front end of a cylinder 3 and has a hole 01 through which a reinforcing continuous fiber bundle impregnated with a thermoplastic resin passes; an inlet die 2 is attached to the rear end of the cylinder 3 and has a hole 02 through which the fiber bundle passes. The cross-sectional shape of the cylinder 3 is not restricted and can be circular, elliptic, square, and so on. The relationship between the length L (mm) and cross section S (mm ) of the hole 01 of the outlet die 1 satisfies the equation α≡L/[2(S/π) ]>=4. When α is less than 4, resin sags, and α is preferably between 4 and 9. When α exceeds 9, it is difficult for a roving to pass through the hole 01 to deteriorate workability. Although a circle is preferable as the shape of the cross section of the hole 01 of the outlet die 1, optional shapes can be adopted.
