This method, which allows acquisition and computation of geometrical data of at least one pattern associated with an ophthalmic object (6) for manufacturing ophthalmic lenses similar to the object or complementary thereto, is of the type in which a device (12) for acquiring and computing geometrical data is used, which comprises: a transparent support (13) adapted for bearing an ophthalmic object; on one side of the support, means (17) for illuminating this support; on the other side of the support, a video camera (25) adapted for producing a video signal representative of at least one pattern associated with the ophthalmic object laid on the support; and signal processing and analysis means (27) receiving at the input the video signal produced by the camera, and adapted for computing and providing the geometrical data. The method is characterized in that: (a) a verification pattern independent of said geometrical data is traced on the ophthalmic object (6), this verification pattern being asymmetrical relatively to each of two axes perpendicular to each other; (b) the ophthalmic object is positioned on the transparent support (13) of the acquisition and display device (12); and (c) by means of said device (12), said verification pattern is optically captured and analyzed.

A manufacturing control system for an additive, subtractive, or hybrid machining system implements a morphic manufacturing approach that integrates in situ inspection and related decision-making into the manufacturing process. After execution of a machining or deposition operation, the system performs a sensor scan to collect sensor measurement data for the resulting part while the part remains in the manufacturing work cell. The measurement data is compared with an as-designed digital model of the part to determine whether further machining or deposition is necessary to bring the finished part into tolerance with the model. If necessary, the system performs another additive and/or subtractive manufacturing operation on the part based on analysis of the measurement data to bring the part into tolerance. The measured inspection data can be stored in association with each manufactured part for auditing purposes or for creation of part-specific digital twins.

In some examples, an adaptive machining system may include a model comparison unit, a compromise shape determination unit, and a program modification unit. The model comparison unit can be configured to compare electronic measured dimensional surface data of a component with an electronic surface model of the component. The compromise shape determination unit can be configured to determine a compromise shape for the component based on the comparison. The program modification unit can be configured to modify a machine tool program code based on the compromise shape.

A method includes receiving a design surface data set, obtaining a component surface data set from the inspection of a component, creating a modified surface data set in response to the design surface data set and the component surface data set, generating a machining path in response to the modified surface data set, and machining the component in response to the machining path to produce a machined component according to the modified surface data set. The machined component deviates from the design surface data set.

A camera photographs a part to be estimated, which is produced by cutting a sheet metal in advance, and a dimension reference marker. An image processing unit generates edge data by extracting an edge of the part photographed by the camera, and enlarges or reduces the edge data based on a size of the dimension reference marker photographed by the camera such that a size of the edge corresponds to an actual size of the part. A machining time calculation unit calculates a length of a cutting line for cutting out the part from the sheet metal based on the edge of the edge data corresponding to the actual size of the part, and calculates a machining time for producing the part by cutting the cutting line in accordance with a material and a thickness of the sheet metal.

A software application executable on a machine tool system for machining a workpiece is configured for executing the steps of: instructing an image recording device to capture an image of a first workpiece having one or more hand-drawn notations, associating the one or more notations with at least one machining step of the machine tool system, presenting on a display device the at least one machining step of the machine tool system on or in relation to the captured image, and/or the first workpiece as the first workpiece will appear after machining the first workpiece according to the at least one machining step of the machine tool system, and optionally controlling a tool of the machine tool system for machining the first workpiece according to the one or more notations.

A method and system provide for reducing gaps between two mating parts. Either or both parts may be nondestructively inspected at a plurality of locations on a surface to gather a data set relating to the part thickness. The data set may be used to calculate a set of as-built thickness values for the part and a set of deviations from a design model. A mating area may be determined for mating surfaces of the parts. One or more layers of sacrificial material in the mating area may be prepared for any deviations greater than a design allowance. The system may include a ply cutting device and an additive manufacturing device coupled to a computer to receive the sacrificial material layer data and shim data and to cut the one or more layers of sacrificial material and to construct the shim. A shim may be constructed for any deviations equal to or greater than a minimum shim thickness. The one or more layers of sacrificial material may be applied to the part, cured, and machined to a desired thickness. The shim may be applied between the part surfaces. The parts may be fitted and assembled together.

A manufacturing control system for an additive, subtractive, or hybrid machining system implements in situ part inspection to collect as-built metrology data for a manufactured part while the part remains in the work envelop, and uses the resulting measured inspection data to generate an as-built digital twin that accurately models the finished part. After execution of a subtractive and/or additive tooling operation, the system performs a sensor scan to collect three-dimensional imaging measurement data for the resulting manufactured part while the part remains in the work cell. The measurement data is then integrated with as-designed part metadata for the idealized part to yield the as-built digital twin. Since metrology measurements are integrated into the manufacturing process, customized as-built digital twins can be generated for each manufactured part without requiring manual inspections to be performed on each part.
