  • Patent number: 10300570
    Abstract: Automated fixture layout is approached in two distinct stages. First, the spatial locations of clamping points on the work piece are determined to ensure immobility of the fixtured part under any infinitesimal perturbation. Second, spatial locations are matched against a user-specified library of reconfigurable clamps to synthesize a valid fixture layout or configuration that includes clamps that are accessible and collision free. The spatial locations matching during the second stage can be the same spatial locations chosen in the first stage to ensure immobility, or a different set of spatial locations.

  • Publication number: 20190094108
    Abstract: A self-aware machine platform is implemented through analyzing operational data of machining tools to achieve machine tool damage assessment, prediction and planning in manufacturing shop floor. Machining processes are first identified by matching similar processes through an ICP algorithm. Machining processes are further clustered by Hotelling's T-squared statistics. Degradation of the machining tool is detected through a trend of the operational data within a cluster of machining processes by a monotonicity test, and the remaining useful life of the machining tool is predicted through a particle filter by extrapolating the trend under a first-order Markov process. In addition, process anomalies across machines are detected through a combination of outlier detection methods including SOMs, multivariate regression, and robust Mahalanobis distance. Warnings and recommendations are flexibly provided to manufacturing shop floor based on policy choice.

  • Publication number: 20190079491
    Abstract: According to some embodiments, an industrial asset item definition data store may contain at least one electronic record defining the industrial asset item. An automated support structure creation platform may include a support structure optimization computer processor. The automated support structure optimization computer processor may, for example, be adapted to automatically create support structure geometry data associated with an additive printing process for the industrial asset item. The creation may be performed, according to some embodiments, via an iterative loop between a build process simulation engine and a topology optimization engine.

  • Patent number: 10061870
    Abstract: A system and a method automate metrology, measurement, and model correction of a three dimensional (3D) model for 3D printability. Slices of the 3D model are received or generated. The slices represent 2D solids of the 3D model to be printed in corresponding print layers. Medial axis transforms of the slices are calculated. The medial axis transforms represent the slices in terms of corresponding medial axes. A local feature size at any point along a boundary of the slices is determined as the shortest distance from the point to a corresponding medial axis.

  • Publication number: 20180173203
    Abstract: Some aspects are directed to additive manufacturing systems. An example additive manufacturing system controller is configured to receive a build file comprising instructions for controlling the manufacturing hardware to generate the object, receive a material identifier indicating a particular lot of manufacturing media, validate the build file and the material identifier via a distributed ledger to verify at least one of an author of the build file or an origin of the particular lot of manufacturing media, control the manufacturing hardware using the build file to generate the object using the particular lot of manufacturing media, and in response to completion of the generation of the object, generate an object manufactured transaction to the distributed ledger indicating a result of the validation of the origin of the at least one of the build file or the material identifier.

  • Publication number: 20180108178
    Abstract: A method for inspecting a component includes generating measurement data of the component, using a measurement device coupled to an optical marker device. The method further includes generating co-ordinate data of the measurement device, using the optical marker device and at least one camera. The method includes generating synchronized measurement data based on the measurement data and the co-ordinate data. The method further includes retrieving pre-stored data corresponding to the synchronized measurement data, from a database. The method also includes generating feedback data based on the pre-stored data and the synchronized measurement data, using an augmented reality technique. The method includes operating the measurement device based on the feedback data to perform one or more measurements to be acquired from the component.

  • Publication number: 20170011301
    Abstract: In various example embodiments, a semantic modeling server includes a semantic model and an inductive logic programming module. The semantic module includes underlying data that defines one or more characteristics of a part to be manufactured. The inductive logic programming module is provided with positive and negative examples of a feature to be identified and part data that defines the part to be manufactured. Given the examples of the feature and the semantic model, the inductive logic programming module determines various rules that can be used to identify whether the provided part data includes the feature defined by the semantic model. Using the determined rules the inductive logic programming module then identifies instances of the feature associated with the semantic model within the provided part data. The inductive logic programming can then be iteratively executed with the semantic model to refine the determined rules.
