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.

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

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.

A method of making a brake caliper housing includes providing a first die and a second die that cooperate to define a cavity when disposed against each other along a mating plane. The method further includes introducing molten material into the cavity to cast the brake caliper housing. One or more surfaces of the brake caliper housing may be machined.

I disclose a method for increasing a quantity of gas bubbles in a head of foam of a beverage in drink ware, comprising providing and sinking a portable nucleation accessory into the beverage. The nucleation accessory features a plurality of nucleation sites etched into a smooth outer surface of the accessory. Each nucleation site comprises a pit which pulls and aggregates gases out of solution until the gases forms a bubble. When the bubble becomes sufficiently buoyant, it detaches from the nucleation site and rises to an upper surface of the beverage. A plurality of nucleation sites producing bubbles in this way build a head of foam on the upper surface of the beverage. Nucleation sites may be arranged to appear as lines or areas to a naked eye.

A metal plate includes a machining subject surface. The metal plate includes a first holding portion designed to be held by a chuck and a second holding portion located at a position separated from the first holding portion and designed to be held by the chuck. The method for manufacturing the metal plate includes performing reference surface machining that machines a surface of the second holding portion that is to be held by the chuck into a predetermined shape in a state in which the first holding portion is held by the chuck. The method includes releasing the first holding portion from the chuck and holding the second holding portion with the chuck. The method also includes machining the machining subject surface in a state in which the second holding portion is held by the chuck.

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

A method for cutting a substrate of irregular pattern comprises: forming a cutting line on the substrate, wherein the closed region enclosed by the cutting line is the irregular pattern that is required; forming a trough line at the cutting line; and applying an external force to the substrate so as to divide the substrate at the trough line. The method can remarkably improve accuracy and efficiency of cutting a substrate of irregular pattern.
