A tooling system, such as an additive manufacturing system, includes a tool displacement mechanism mounted on a fixed structure and carrying a system tool such as a printhead. The tool displacement mechanism displaces the system tool along a curvilinear closed path about a system axis and located within a working plane intersecting the system axis. A bed, connecting to the fixed structure, is substantially positioned within the working plane, locally adjacent the closed path and along at least a portion of the closed path.

A system may be configured to manufacture a layered cage of a trim. Some embodiments may additively manufacture, in each of a plurality of layers, a plurality of channels each having a cross section such that an amount of the layers satisfies a criterion, the cross section being defined by vertical walls, angular portions that extend from the walls, and a shaped top and/or bottom intersecting with angular portions. And the channels of one of the layers may not intersect with any other channel of any other layer of the cage.

A composition of a copper alloy for a laser cladding valve sheet is disclosed. The copper alloy includes a matrix structure and a hard phase, which includes 12 to 24 wt % of Ni, 2 to 4 wt % of Si, 8 to 30 wt % of Fe, more than 5 wt % and less than 10 wt % of Mo, 2 to 10 wt % of Al, and the balance Cu. The interfacial delamination may be suppressed in a fatigue environment by micronizing the hard phase and the distribution thereof, thereby improving fatigue resistance and wear resistance.

A composite member is manufactured by a manufacturing method including adding, on a surface of a base member composed of a first material, a second material different from the first material, using additive manufacturing employing directed energy deposition as an additive manufacturing process. The manufacturing method is performed by placing the base member in a machining area of a machine tool configured to perform subtractive machining. Accordingly, a composite member can be obtained that is manufactured through additive manufacturing and that is in a state in which the composite member can be promptly machined.
