摘要:
A method and apparatus for measuring diameters of holes and countersinks. A tip of a countersink measurement system may be moved to engage a countersink for a hole. A diameter of the countersink may be measured in response to the tip of the countersink measurement system engaging the countersink. A probe may be moved through the tip of the countersink measurement system into a channel for the hole, while the tip is engaged with the countersink. A number of diameters for the channel may be measured as the probe moves in the hole.

A self-contained crawler assembly is engageable to a stringer and is adapted to position a drill bushing along the stringer for performing machining operations. The crawler assembly includes a longitudinal slider, a lateral slider and a controller for regulating operation of the longitudinal and lateral sliders for positioning the drill bushing at a hole location. In a further embodiment, the crawler assembly may include a longitudinal friction drive which is directly engageable to the stringer and which is operative to move in a direction parallel to the stringer.

A crawler assembly includes an attachment mechanism that is removably attachable to a stringer. The stringer has a vertical web and a longitudinal axis. The crawler assembly includes a longitudinal slider that is engageable to the attachment mechanism and having a normalizing mechanism disposable in bearing contact against the vertical web for maintaining an orientation of the longitudinal slider relative to the stringer. The longitudinal slider is movable along a direction parallel to the longitudinal axis. The crawler assembly includes a lateral slider that is mountable to the longitudinal slider and is movable along a direction perpendicular to the longitudinal axis. The lateral slider includes a drill bushing. The longitudinal and lateral sliders cooperate to move the drill bushing to at least one predetermined hole location.

摘要:
A computer-based method for defining a surface of a part for placement adjacent a mating surface of a base part is described. The method includes receiving raw data which defines the mating surface of the base part, smoothing the raw data, generating a stable reference frame consisting of at least one of a substantially smooth curve and surface based on the smoothed raw data, calculating a dimensional offset curve or surface using the smoothed raw data and the stable reference frame curve or surface by referencing any peaks in the smoothed raw data within a predefined range of a corresponding point in the stable reference frame curve or surface, smoothing the dimensional offset curve or surface, and outputting the dimensional offset curve or surface for utilization in fabricating the part that is to be adjacent the base part.
