Abstract: A computer-implemented method for marking an object on an aligner. The aligner surface is modeled. The method includes calculating a normal for each tile in a tessellated surface and disqualifying a tile from being selected. For tiles not disqualified, a patch is identified that produces a markable area. The method includes selecting an object to be marked, calculating a location of the object in the markable area, and providing the location of the object to a marking device. Disqualifying includes comparing an angle between a normal and an orientation of the beam to an origin of the calculated normal on each tile. Disqualifying includes disqualifying the at least one tile when the angle is outside of a range of ?90° to +90°. Identifying the patch includes separating the patch into at least two smaller patches, and one of the two smaller patches of tiles is the markable area.

Abstract: A fastening system including a bolt with a shank defining a bolt axis and a bolt head secured to the shank.

Abstract: A method of assembling a vehicle is disclosed, comprising the steps of (in sequence) providing a chassis structure, affixing a door inner panel to the chassis structure via a hinged attachment, at a location adjacent to a door opening defined by the chassis structure, attaching at least one external body panel to the chassis structure, attaching a door outer panel to the door inner panel via an adhesive fixing. In this way, the door inner panel can be attached in place during the build, at a position tailored to the needs of the seals provided between the door and the chassis structure. Production of the vehicle can continue, and in due course the exterior body panels can be fitted to the chassis structure. The door outer panel can then be attached to the door inner panel, using the tolerance in the adhesive attachment to adjust for panel gap and flushness of fit. The application also relates to a vehicle made in this way.

And an axial circular recess is partially defined in a transition portion between the head and the shank.

Abstract: A method for manufacturing a component of a rotary machine, the component extending to an axial direction and a radial direction vertical thereto, and has an inner channel, extending from a first end of a core of a center of the component and to a second end at a radial limiting surface of the component and which is at least partially closed. A blank includes the core of the component and is limited by an outer surface in the radial direction. The blank is subtractively processed in a first subtractive process step, such that an outer contour is elaborated in the area of the outer surface, which extends in the radial direction, and a part of the channel is manufactured, which radially extends in the blank to the first end. The channel is finished by a build-up process on the blank.
