Every junction part for an airplane wing is manufactured with overmaterial. Each part is measured with a laser based interferometer or other scanning technique and the as built measurements are compared with a model to generate a new trajectory milling program to fill or prevent gaps between parts using a points cloud and B-Spline algorithm to generate a new surface to be milled. Once the program is generated (new trajectories) and post processed, it is sent to a milling machine to perform overmaterial milling on already milled parts with overmaterial. This technique can be used to eliminate gaps between junction parts and the corresponding need for shims.

A cutting insert has an upper surface (21), a lower surface (91) and a side surface (61) that connects the two surfaces. A cutting edge is formed at an intersecting edge between the upper surface (21) and the side surface (61). The cutting edge includes at least a major cutting edge (33), a corner edge (34) connected to the major cutting edge (33), and a curved wiper edge (35) located on the opposite side of the major cutting edge (33) across the corner edge (34). A first angle made by the major cutting edge (33) and the chord of the wiper edge (35) is 155<180, and a positive land is formed in the wiper edge (35). The cutting edge may further include an inner cutting edge (36) located on an opposite side of the corner edge (34) across the wiper edge (35).

A method and a system are disclosed for making an article of manufacture from a blank defining an internal opening. A stack of blanks are aligned and the internal openings of the blanks in the stack of blanks are machined by a rotary cutting tool to a finished dimension. The blanks are clamped together before machining in a numerically controlled machine tool. The blanks are subsequently formed individually in a sheet metal forming operation in which the inner perimeter of the internal openings is expanded as the blank is formed.

Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A method and related system and apparatus for refurbishing worn rail transit rails to a desired refurbished rail surface profile substantially similar to the surface profile of a newly-manufactured rail, comprising: depositing a first line of fill material along a lower-inside section to be refurbished; in N1 successive iterations thereafter, progressing circumferentially from the lower-inside section to be refurbished to an upper-outside section to be refurbished, depositing an n+1.sup.th line of fill material adjacent an n.sup.th line of fill material wherein the n.sup.th line of fill material substantially provides a flow barrier against the n+1.sup.th line of fill material flowing past the n.sup.th line of fill material.

A method of forming a curved slot in a turbine disk includes the steps of forming a pre-slot in the turbine disk and finishing the pre-slot to form a slot that receives a portion of a turbine blade. The turbine disk including a first face, an opposing second face, and an outer perimeter surface extending between the first face and the opposing second face. The pre-slot includes a first curved wall and a second curved wall that each extend between the first face and the opposing second face. An intersection between the outer perimeter surface and each of the first curved wall and the second curved wall is defined by a curved line.

An apparatus and method for processing anode plate for electrolysis, the apparatus includes a transverse transmission device (3) for transmitting the anode plate in a transverse direction; a plate-flattening and thickness-measuring device (4) for flattening the anode plate and measuring a thickness of the anode plate; a hanger bottom milling device (6) configured to mill a bottom surface of a hanger of the anode plate, disposed at a first side of the transverse transmission device (3) and positioned downstream of the plate-flattening and thickness-measuring device (4) in the transverse direction; and a hanger side milling device (5) configured to mill a side surface of the hanger of the anode plate, disposed at a second side of the transverse transmission device (3) and positioned downstream of the plate-flattening and thickness-measuring device (4) in the transverse direction.

Methods and structures for forming anodization layers that protect and cosmetically enhance metal surfaces are described. In some embodiments, methods involve forming an anodization layer on an underlying metal that permits an underlying metal surface to be viewable. In some embodiments, methods involve forming a first anodization layer and an adjacent second anodization layer on an angled surface, the interface between the two anodization layers being regular and uniform. Described are photomasking techniques and tools for providing sharply defined corners on anodized and texturized patterns on metal surfaces. Also described are techniques and tools for providing anodizing resistant components in the manufacture of electronic devices.

A rail vehicle includes a milling device for finishing the running surface of track rails during the travel of the rail vehicle along the track rails. The rail vehicle has a chassis frame having wheel sets. The milling device is provided with a milling head, and includes a framework arranged on the chassis frame having a milling head receptacle, which is displaceable vertically and transversely in relation thereto. The milling head receptacle can be supported for the vertical guiding via a guide shoe on the running surface and for transverse guiding in parallel to the milling head shaft via a guide stop laterally on the railhead. The milling head receptacle forms a transverse carriage, which supports the guide shoe and the guide stop, and the guide path of which, which is vertically displaceable, is provided on the side of the milling head receptacle facing toward the guide shoe.
