Abstract: A method of making hollow turbomachine components is disclosed. The method provides for an additive manufacturing step, wherein on a substrate the following are manufactured in sequence: a first terminal portion of a semi-finished component, said first terminal portion adhering to said substrate, an intermediate portion adjoining the first terminal portion, and a second terminal portion adjoining the intermediate portion. After cooling of the component, at least one of said first terminal portion and second terminal portion is removed. The removed terminal portion includes sacrificial features, where thermally induced deformations of the component are concentrated, or which are aimed at stiffening the component, such that deformations are reduced or prevented.

Abstract: An apparatus for performing an industrial working operation on a workpiece comprises: an anthropomorphous robot comprising an end effector including a 2D laser scanner and a working tool; an RTOS computer; and a robot controller. The computer provides successive positional data along a scanning path to robot controller, and a synchronization signal directly to input port of the 2D laser scanner, thereby commanding successive scanning operations on the workpiece in synchronism with successive poses of the end effector, to acquire 3D shape information about the workpiece. The working tool is operated while the end effector is subsequently moved along a tooling path and/or is moved along a combined scanning and tooling path. An apparatus for acquiring a shape of an object arranged at a working area and methods are further disclosed.

Abstract: A cutting head for a mill configured to rotate about an axis to remove material from a work piece includes a base surface, a side region connected to the base surface, and a top region connected to the side region. The top region defines a central area and a periphery. A plurality of top teeth are disposed on the top region. The top teeth have cutting edges configured to contact the work piece to remove material. Each cutting edge extends from the central area towards the periphery and includes an axially extending peak portion.
