20080319557 | Program-Controlled Process - A drilling machine drills at a multiplicity of target locations on a component. Two robots, calibrated with calibration data, move the component in a 6-D coordinate system. A metrology system ascertains the position of the component relative to the drilling machine. The movement of the robots is effected by means of commands generated by means of off-line programming. The component is moved relative to the drilling machine to a target position, ready for drilling, by means of a closed-loop process in which the differences in position between the expected position (the target position) and the actual position (as viewed by the metrology system) are corrected. | 12-25-2008 |

20110286478 | LASER SCAN SPEEED CALIBRATION - The invention relates to a method of verifying a scan speed in a laser scanning system. The method includes modulating the laser of the system to form a periodically modulated feature from which the actual scan speed can be read or deduced. | 11-24-2011 |
20120100030 | HEAT TREATMENTS OF ALM FORMED METAL MIXES TO FORM SUPER ALLOYS - A method of forming an article includes forming a layer of a mixture of at least two distinct metal powders selected such that when combined they are chemically in the proportions of a superalloy containing a gamma prime phase, and fusing the powders locally without diffusion to define the shape of a part of the article such that the materials of the distinct metal powders remain substantially chemically segregated forming regions of different chemical composition. The method further includes repeating the forming and fusing until the derived article is formed, and heat treating the finished article such that at least one of the distinct separate materials diffuses to form a gamma prime phase containing superalloy with the other. | 04-26-2012 |

20130270750 | APPARATUS AND METHODS FOR ADDITIVE-LAYER MANUFACTURING OF AN ARTICLE - Apparatus is for additive layer manufacturing of an article from a material which can be rendered solid locally by application of a focused beam of laser radiation at a planar focal plane. The apparatus includes at least two laser beams, respective scanners for each laser beam for scanning the respective laser beams over a planar field, and a support movable stepwise to allow successive manufacturing layer cycles and for supporting material within the field. The entire planar field is common to each scanner and at least one scanner is tilted with respect to the planar field, and the at least one scanner is provided with a lens arranged to generate a focal plane tilted with respect to that scanner. | 10-17-2013 |

20090151888 | Core for casting - A core for casting a container comprising a casting surface, where the core is divided into at least two core segments. The casting surface of each core segment adjoins a division surface, and the division surface of each core segment is spaced apart from the division surface of a neighbouring core segment by a gap. The gap is spanned by a frangible collapsible member such that substantially all of the casting surface is free of the collapsible member. | 06-18-2009 |

20120253741 | CHECKING POSITIONAL ACCURACY OF FEATURES - A component such as a casing of a gas turbine engine has an array of holes distributed around a flange. The casing may distort when unsupported, but nevertheless the position accuracy of the holes may be checked by manipulating measured hole positions to lie with known deviations from a best-fit circle. The maximum load and stress required to bring the hole array into conformity with the best-fit circle is calculated and compared with a predetermined maximum. The deviation of the hole positions associated with the best-fit circle from nominal positions can also be calculated. | 10-04-2012 |
20130156557 | SHAPING APPARATUS AND METHOD OF SHAPING A WORKPIECE - A shaping apparatus for shaping a workpiece. The apparatus comprises first and second pairs of shaping members and a spacer located between the first and second pairs of shaping members. The first pair of shaping members comprises a material having a first linear coefficient of thermal expansion, and the second pair of shaping members comprises a material having a third linear coefficient of thermal expansion. The first linear coefficient of thermal expansion is higher than the second linear coefficient of thermal expansion such that on heating of the apparatus, thermal expansion of the shaping members causes the first pair of shaping members to expand outwardly, and the second pair of shaping members to expand inwardly. | 06-20-2013 |
