Appl. No.:

09/583938

Inventors:

Michael Evans Graham - Slingerlands NY
Dean Michael Robinson - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

G06K 936

US Classification:

382276, 382155, 382173, 703 1, 700182, 700193

Abstract:

A method of nesting a computer model of a part ( ) into a computer model of a fixture ( ) useful for situations where the original positions of the part and fixture are completely separate and for situations where the respective part and fixture surfaces overlap. The model of the fixture is first inset by a distance D sufficient to eliminate any overlap between the modeled surfaces. The minimum normal distance segment ( ) between the inset fixture surface and the part surface may then be determined using standard CAD system capabilities. A vector is then constructed having a length D beginning at the minimum distance point on the inset fixture surface ( ) and extending in the direction of the minimum normal distance segment ( ) to a point ( ) on the original fixture model surface ( ). The minimum distance segment between point ( ) and the surface of the part ( ) is then determined to identify a point ( ). The respective point pair ( ) is recorded.

International Classification:

G06F 1500

US Classification:

702155, 700103

Abstract:

A method for performing geometric dimension and tolerance stack-up analysis for an assembly, the method comprising receiving a target assembly dimension for stack-up analysis, where the assembly includes at least one part. The method further comprises receiving a feature corresponding to the part and receiving feature tolerance data associated with the feature. The feature tolerance data includes at least one of size tolerance and geometric tolerance. Stack-up rules are accessed in response to receiving the feature tolerance data. The stack-up rules include instructions to determine if a form tolerance, an orientation tolerance and a profile tolerance should be included in a stack-up tolerance for the feature. The stack-up rules also include formulas to calculate a nominal dimension and the stack-up tolerance for the feature when the feature tolerance data applies to features of sizes. The nominal dimension and the stack-up tolerance are derived in response to the stack-up rules and the feature tolerance data.

Abstract:

A method for integrating a measurement device for use in measuring a machine component includes providing a coordinate measuring device, such as a coordinate measuring machine (CMM), and integrating with a plurality of nondestructive examination (NDE) capabilities with a plurality of coordinate measuring device capabilities to form an inspection probe. The method further includes integrating the NDE inspection probe with the coordinate measuring device such that the inspection probe substantially simultaneously measures a plurality of NDE measurements and external/internal geometry and defects of machine component, which are linked to actual component dimensional information provided by CMM. The inspection data can be simultaneously linked to and/or displayed together with a CAD model to enable a direct comparison between the inspection data and the nominal requirements carried on the CAD model.

US Classification:

36447415

Abstract:

A method for determining an adaptive feedrate for a machine tool used to machine a workpiece initially cut from stock using a stock-cutting program. Initial workpiece geometry is obtained from a geometry modeling program using the stock-cutting NC program as an input. Such automatically-generated initial workpiece geometry is used to derive adjusted (i. e. , adaptive) feedrates in accordance with a known method.

International Classification:

Abstract:

A compensation field indicating an amount of distortion compensation to be applied across at least a portion of a component is determined, and a nominal computer-aided design (CAD) model of a component is modified based on the compensation field. The amount of distortion compensation corresponds to a multiplication product of: (i) a deviation between the nominal CAD model and a physical representation of the component having been produced based on the nominal CAD model, and (ii) a nonlinear scale factor map that includes a map associating a plurality of locations of the nominal CAD model to corresponding ones of a plurality of scale factors respectively representing an increase or a decrease in the amount of distortion compensation to be applied based on a simulated effect upon the component in response to an iterative simulation process.
