A method of making a tailored blank comprising the following steps: (a) friction welding first and second structural members together at a substantially right angle with respect to each other to form an intersection comprising a first joining surface formed by adjoining bottom faces of the first and second structural members, and a second joining surface formed by an angled face of the first structural member that is disposed at a first oblique angle relative to the bottom face of the first structural member; (b) friction welding the first joining surface of the intersection to a first portion of a surface of a base member; and (c) concurrently linear friction welding first and second joining surfaces of a third structural member to the second joining surface of the intersection and to a second portion of the surface of the base member respectively.

A fixture is used to mount an angled machine head on a machine tool. The fixture includes a base adapted to be mounted on the machine tool, and a collar for holding the angled machine head. The collar is mounted for rotation on the base and allows the angled machine head to be rotated to any of a plurality of rotational positions. The collar may be selectively locked to the base to fix the position of the angled machine head.

A method of making tailored blanks in accordance with one embodiment comprises the steps of friction welding a first joining surface of a first structural member having a substantially non-rectangular parallelogram profile to a first portion of a joining surface of a substrate; and thereafter concurrently linear friction welding first and second joining surfaces of a second structural member having a substantially non-rectangular parallelogram profile to a second portion of the surface of the substrate and to a second joining surface of the first structural member respectively. The first and second portions of the surface of the substrate are adjacent. Two or more structural members having a substantially non-rectangular parallelogram profile can be linear friction welded in succession to the substrate and to each other, thereby building a structural assembly having a long flange or other long feature of a desired length.

A method of friction welding in accordance with one embodiment comprises the steps of inserting a protruding portion of one structural member into a groove of another structural member, and then friction welding the two structural members together to form a non-planar weld joint at an interface of the protruding portion of the one structural member and the groove of the other structural member. The groove can be linear or arc-shaped. The friction-welded members may form an acute or right angle.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

A computer implemented apparatus and method for receiving tool paths that a dispensing head follows to deposit roads of material for successively building object layers of a 3D object during an additive manufacturing process, generating simulated object layers of a simulated 3D object from the tool paths, wherein the simulated object layers represent an interior geometry of each one of the object layers, determining a contact surface area between adjacent ones of the simulated object layers, and determining a predicted mechanical property of the 3D object from the contact surface area and a material property of the material.

A unitized assembly may comprise a fiber metal laminate and at least one additive layer. The fiber metal laminate may have non-metallic plies bonded to metallic plies and may include an innermost metallic ply. The at least one additive layer may be deposited onto the innermost metallic ply by friction stir welding.
