A method for machining a metallic member to provide a finished appearance uses a lathe and a scraping process. A metallic member comprising a top portion and a peripheral sidewall is provided, the metallic member is positioned on the worktable. The worktable is rotated with the metallic member, the lathe tool moved backwards and forwards to machine the top portion of the rotary metallic member circumferentially. The lathe tool is moved by the moving device along a predetermined path relative to the worktable to machine curved surfaces of the top portion of the metallic member. The scraping cutter is moved to contact the peripheral sidewall of the metallic member. The scraping cutter is moved along a predetermined path, and the scraping cutter is fed the metallic member to achieve the required shape and finish.

A laser welding method includes a pretreatment process and a welding process. At least one metal member of the plurality of metal members is formed from a metal-plated steel plate in which a base metal has been covered with a coating material that has a melting point lower than the base metal. In the pretreatment process, with the position of the first metal member in the in-plane direction fixed, processing is performed from the front surface of the first metal member to form on the back surface, a protrusion that bulges from the back surface. Then, in the welding process, the first metal member in which a protrusion has been formed is superposed on a second metal member with the protrusion therebetween while maintaining the position in the in-plane direction, and laser light is irradiated on the superposed region to weld the plurality of metal members to each other.

A top case assembly for a portable computer is disclosed. The assembly may include an integral unified (e.g., homogenous) top case formed from a single part. The integral top case provides an enclosure, frame and cosmetic exterior of the portable computer. The integral top case also serves as the primary structure of the portable computer. The assembly may include a variety of subassemblies such as keyboards, touchpads, circuit boards, and drives that are carried by the underside of the integral top case. The integral top case may be formed from aluminum slab that has been machined to form walls, openings, attachment areas and cosmetic areas of the top case.

Methods of creating a hook for a bike rack. The methods include the steps of providing a planar metal material, cutting a two-dimensional shape from the planar metal material where the two-dimensional shape defines a hook precursor, forming the hook precursor into a three-dimensional hook where the three-dimensional hook includes a hook face, and adding a protective layer to the hook face. In some examples, the methods include processing the three dimensional hook to remove sharp edges, cutting a mounting point into the hook precursor, cutting a bevel on an edge of the hook precursor to define a beveled edge, and/or cutting a curve on an edge of the hook precursor to define a rounded edge.

A method of forming a universal bellhousing which may be adapted to a variety of automotive engine and transmission combinations is disclosed. The bellhousing is made by spin forming a sheet of material and welding a transmission plate to the cone. The cone and transmission plate are indexed to mount to a specific, desired engine-transmission combination.

A compound barb medical device is provided which includes an elongated body having at least one barb formed along the length of the body, the barb defining an inner surface with a first portion disposed at a first orientation relative to a longitudinal axis of the elongated body, and a second portion disposed at a second orientation relative to the longitudinal axis. Optionally, the barb defines a third portion disposed at a third orientation relative to the longitudinal axis. A method for forming a compound barb on a medical device is also provided.

Methods, system, devices, processes and techniques are disclosed for manufacturing orthopedic implants utilizing blanks and/or fixtures.

Machining ball tracks and guiding webs of an inner part for a constant velocity joint in a clamping arrangement includes mechanical machining of at least one first ball track in a first rotational position; rotating the articulated inner part into a second rotational position for machining at least one further ball track; wherein at least one guiding web is mechanically machined during the rotating of the inner joint part from the first rotational position into the second rotational position. A corresponding device is used for machining ball tracks and guiding webs of an inner joint part.

A gas flow can be provided together with a liquid jet guided laser beam to remove accumulated liquid on the processing surface. The gas flow can be configured to have minimum interference with the liquid jet guided laser beam, while functions to blow away liquid generated by the liquid jet. Keeping the surface free from accumulated liquid can improve the efficiency of the liquid jet guided laser processing.

A blank for use in manufacturing a surgical implant is provided. The blank includes a shape based, at least in part, on one or more features common to a specific type of patient-adapted implants. The blank has dimensions that are equal to or larger than corresponding dimensions of each patient-adapted implant included in the specific type of patient-adapted implants.
