Abstract: A method is provided for inspecting at least one aperture of a component with curable material and an inspection system. At least a portion of the curable material is injected into the aperture. The curable material conforms to at least a portion the aperture and subsequently cures and forms a mold of at least a portion of the aperture. The mold is removed from the aperture. At least a portion of a geometry of the mold is compared to at least a portion of a geometry of a reference model for the aperture using the inspection system.

Abstract: A method is provided for inspecting a plurality of parts with an electronic measurement device and a processing system. The method includes a step of creating surface geometry maps of the parts utilizing the electronic measurement device, where each part was manufactured utilizing the manufacturing device. Geometric part models of the parts are generated from the surface geometry maps. The part models can subsequently be analyzed to determine whether a manufacturing device that manufactured the plurality of parts manufactures parts that comply with a part design specification.

Abstract: A method for inspecting a surface geometry of a workpiece includes mounting the workpiece to a measurement artifact that includes a plurality of parametric datum features. The parametric datum features may be utilized by a first inspection device and a second inspection device to establish a measurement coordinate system. The surface geometry is measured relative to the measurement coordinate system with the first inspection device to provide first measurement data. The surface geometry is also measured relative to the measurement coordinate system with the second inspection device to provide second measurement data.

Abstract: A method for inspecting geometrical shapes of objects to determine selected dimensions thereof based on data characterizing such objects obtained through stereoscopic photographs taken by a pair of cameras with fields of view intersecting to thereby provide a photographic event measurement volume that includes at least a portion of each of such objects being photographed. The method involves using previously specified procedures to check on the cameras performance consistency in photographing from different positions, preparing the object to be inspected including providing reference point targets thereon, scanning that object with the cameras from different camera pair positions, processing the resulting data to represent the scan basis geometrical shape of the object, and orient it to compare with the dimensional specifications therefor.

Abstract: A centrifugal fuel distributor including a drive shaft rotatably mounted within a housing having a distribution cavity. A sidewall of the distribution cavity defines a plurality of spaced-apart fuel outlets, and a hollow armature is biased radially outwardly from the drive shaft, so that a distal end of the armature is in sealing contact with an inner surface of the sidewall. During operation, pressurized fuel travels through a fuel passage in the drive shaft and through the hollow armature while the drive shaft is rotated, so that the distal end of the armature slides along the inner surface of the sidewall of the distribution cavity and sequentially distributes fuel to the plurality of fuel outlets. The fuel then passes from each fuel outlet to fuel injectors mounted in cylinders of an engine incorporating the fuel distributor.

Abstract: A fuel distributor for delivering fuel under pressure to cylinders of an engine. The distributor includes a housing, an inlet for delivering fuel under pressure to the housing, a plurality of outlets in the housing and a valve assembly mounted in each outlet. Each valve assembly is for connection to a fuel injector mounted in a cylinder of the engine, and each assembly includes a passage for delivering fuel under pressure from the housing, a plunger positioned in the passage, and a valve spring biasing the plunger to one of a passage open position and a passage closed position. The fuel distributor also includes a cam for moving the plungers against the valve springs, whereby movement of the cam controls fuel flow to the cylinders.
