Abstract: A system is configured for machining a workpiece (100), the workpiece includes an interior surface (110) that defines an internal passage (112). The system includes an electrode (116) located within the internal passage and electrically isolated from the workpiece, an electrolyte supply, a power supply, and a remover. The electrolyte supply is configured for circulating an electrolyte in a gap between the electrode and the workpiece. The power supply is configured for applying a voltage between the electrode and the workpiece to facilitate smoothing the interior surface. The remover is configured for completely removing the electrode from within the internal passage after smoothing the interior surface.

Abstract: The subject matter disclosed herein relates to additive manufacturing techniques, and more specifically, to additive manufacturing techniques that involve binder jet printing. A disclosed additive manufacturing system for fabricating an article includes a build unit and a positioning system operably coupled to the build unit. The positioning system is configured to move the build unit in at least three dimensions. The build unit includes a recoater portion configured to deposit a layer of powder within a build area of the additive manufacturing system. The build unit also includes a binder jetting portion configured to selectively deposit and cure a binder within a periphery of the deposited layer of powder to form a dynamic build envelope around the article being fabricated in the build area.

Abstract: A system and method including receiving a data model representation of a part, the data model representation including at least one layer of the part and inner and outer contours for the at least one layer; determining a hatch pattern for each layer of the at least one layer of the part, the hatch pattern for each layer being dependent on the inner and outer contours for each respective layer; generating a record of the determined hatch pattern for each layer, the record including locations for the hatch pattern for each layer; and saving the record of the determined hatch pattern for each layer of the part. In some aspects, the record of the determined hatch pattern for each layer of the part may be used in an additive manufacturing process.
