Abstract: A computing system may include an access engine and a defect detection engine. The access engine may be configured to access a slice contour of a given layer of a 3-dimensional (3D) object designed for manufacture through an additive manufacturing process and obtain hatch tracking for the slice contour, the hatch tracking representative of an energy path to melt metal powder for constructing the given layer through the additive manufacturing process. The defect detection engine may be configured to construct, from the slice contour, an as-built image for the given layer by rendering the hatch tracking in the slice contour; construct, from the slice contour, an idealized image for the given layer; and identify defects in the given layer via image analysis between the as-built image and the idealized image.

Abstract: A machining method is provided for manufacturing a feature in a part. Feature data are received that describe a feature to be manufactured and include a type and a set of attributes of the feature. Machining method data are received that describe a machining method for manufacturing an associated feature. Machining methods associated with features of a given type are analyzed in order to define a set of ranges of feature attributes where the machining methods are applicable. A set of ranking values are assigned to each machining method for ordering machining methods. Data of an additional feature to be manufactured is received, the type of the additional feature being the given type and the set of attributes is a specific set. A set of machining methods is selected and at least one machining method is provided based on its assigned ranking value to be associated with the additional feature.

Abstract: Various disclosed embodiments include methods, systems, and computer-readable media for managing feature geometry-aspect machining using a PLM data processing system. According to one embodiment, a method includes identifying a feature geometry in a graphical design. The method also includes identifying an aspect of the feature geometry. The aspect includes a subset of the feature geometry. The method further includes defining the feature geometry aspect based on a user-defined name. The method also includes associating one or more machining operations with the feature geometry aspect. Additionally, the method includes storing the one or more machining operations and the user-defined name in association with the feature geometry aspect.

Abstract: Methods for computer-aided manufacturing and design, and corresponding systems and computer-readable mediums. A method includes receiving a three-dimensional (3D) solid part model and an associated 3D solid blank. The method includes defining an initial in-process workpiece (IPW) as the same as the 3D solid blank, and defining a cut volume in-process feature to be removed from the IPW. The method includes removing the cut volume in-process feature from the IPW. The method can include calculating and storing the cut volume in-process feature or the updated IPW with the removed cut volume in-process feature. The updated in-process workpiece can be calculated and displayed for each state at all times, in various embodiments.
