Every junction part for an airplane wing is manufactured with overmaterial. Each part is measured with a laser based interferometer or other scanning technique and the as built measurements are compared with a model to generate a new trajectory milling program to fill or prevent gaps between parts using a points cloud and B-Spline algorithm to generate a new surface to be milled. Once the program is generated (new trajectories) and post processed, it is sent to a milling machine to perform overmaterial milling on already milled parts with overmaterial. This technique can be used to eliminate gaps between junction parts and the corresponding need for shims.

Provided is an automatic teaching system that is readily able to achieve automation, even when a small but varied number of processing objects are to undergo polishing or coating. The automatic teaching system includes a three-dimensional shape measurement apparatus, a reference marker, an image analysis apparatus, and a robot control device. The three-dimensional shape measurement apparatus acquires shape data of a processing target region on a processing object relative to the reference marker, and the image analysis apparatus divides the shape data of the processing target region into a plurality of continuous reference surfaces, in accordance with a predetermined algorithm, automatically generates a program of an operation path along which a polishing apparatus or coating apparatus of the robot is to be operated, for every reference surface, in accordance with a predetermined operation path generation rule, and transmits the program of the operation path to the robot control device.

This invention concerns improvements in the inspection, assessment and re-working of manufactured components such as nozzle guide vanes (NGVs) and blades, in particular by improving the comparison of the component with nominal data. Dimensional data of a physical component is obtained and used to create a virtual digitized model of the component which is aligned with a nominal CAD model of the component in a virtual space. The correspondence is assessed and used to adjust weightings of different regions of the digitized model to improve the alignment. This process is repeated within the digital space until either conformance is reached or it is determined that this is not possible.

This disclosure relates to a computer-implemented system and related methods for the design, evaluation, and/or manufacture of protective patient footwear, such as shoes, braces, boots, casts, corrective footwear, and orthoses. The system includes suitable hardware, software, and related peripherals, which function to acquire data related to the patient's particular footwear needs, such as by image capture, including three-dimensional scanning. The system may also acquire data through other sources of input, such as through one or more sensors for detecting various physiologic parameters associated with the lower extremity, or through input of medical conditions, prior indicators, exam, analysis, lab results, or the like, such as through medical practitioner input or other input protocols. The various inputs may be suitably processed to generate output in the form of a design accommodation to design or modify the protective patient footwear, or in the form of one or more medical evaluations or recommendations.

The present invention relates to a method and a system for manufacturing a board body (10), such as a skateboard, from a blank (20) having an indefinite shape. The blank (20) with the indefinite shape is collected by a handling robot (50).
