A component machining apparatus includes a measurement result acquiring unit and a machining data generator. The measurement result acquiring unit is configured to acquire a measurement result obtained by a measurer configured to measure a three-dimensional shape of a manufactured component among components of a structure. The manufactured component is manufactured earlier than a component of interest. The machining data generator is configured to generate machining data of the component of interest based on the measurement result of the manufactured component that has been acquired by the measurement result acquiring unit.

A method is described for the computer-aided programming of robots for processing workpieces. According to one exemplary embodiment, the method comprises the generation of a first virtual workpiece by superposing models of several workpiece variants of a workpiece by means of a software tool run on a workstation and the carrying out of path planning for defining tool paths for at least one first region of the workpiece and verifying the defined tool paths on the basis of the first virtual workpiece. Each of the workpiece variants is given by a set of determined local geometric forms of a basic body. The different geometric forms can be formed for example by attachment parts arranged on the workpiece basic body or by modification of the external geometric shape of the workpiece basic body.

The invention relates to a system and a method for precisely fitting component assembly, namely the precisely fitting installation of a second component on a first component. The invention relates in particular to corresponding systems and methods for precisely fitting component assembly of components on motor vehicles. It is achieved that a contact section of a second component and a contact section of an already assembled first component show no offset or no visible edge after assembly.

Systems and methods for retuning a surface to a nominal geometry using local reference points are disclosed. The system can include an imaging device for detecting the location of local features on an object. The system can use the location of local features, as opposed to an absolute reference frame, to determine one or more reference areas and one or more surface defects on an object. The system can then determine a nominal geometry for the surface (i.e., a surface that is substantially free of surface defects) and calculate the tool path necessary to create a nominal geometry. The system can machine the surface and, in some cases, rescan the surface to ensure the operation has machined the part to the nominal geometry.

A system for moving first and second fuselage structures into assembly alignment, the system including a first transmitter indexed to a first seat track of the first fuselage structure, a first reflector target indexed to a first seat track of the second fuselage structure, a second transmitter indexed to a second seat track of the first fuselage structure, a second reflector target indexed to a second seat track of the second fuselage structure, wherein the first and second transmitters and the first and second reflector targets cooperate to provide first and second measurements indicative of position of the first fuselage structure relative to the second fuselage structure, and a manipulator system including at least one assembly actuator coupled to the first fuselage structure to move the first fuselage structure into assembly alignment with the second fuselage structure based upon the first and second measurements.

There is described a method and system for reshaping a component for assembly that may have been deformed pre-assembly and post-fabrication. As-fabricated measurements are used to determine a baseline for the component and as-mounted measurements are used to determine a deformation parameter as a function of the baseline. The component may be reshaped using correction displacements applied to a positioning device of an assembly tool to which the component is mounted for assembly.

A method for optimizing the tolerancing of a set of flexible parts subjected to forces. At the design phase, an optimum tolerancing for flexible parts is defined according to the assembly process plan and the desired functional requirements. The structural digital models are considered as parts to be assembled and composed of a plurality of assembly points, a plurality of structural points, and mathematical relations or mechanical stiffness, such as a non-null relative displacement of a structural/assembly point in relation to the other structural/assembly points in a single digital model, modify tensor in each structural/assembly point. From a mechanical point of view, these mathematical relations express the existence of an elastic recovery property between the points that make up the digital model. The issue of optimization is simplified by: the definition of influence factors; the simulation of parts deviating from the nominal by a distortion vector.

A method, a device, and a computer-readable storage medium is provided for performing the method for automating an assembling sequence operation for a workpiece using an one-up assembly process that uses adjacent hole clamping. The method can include obtaining an adjacency list from points for the workpiece to be assembled; controlling an assembly machine for assembling the workpiece using a sequence of assembly operations based on the adjacency list; identifying potential errors in the sequence of assembly operations; determining a revised sequence of assembly operations based on the potential errors that are identified; and controlling the assembly machine based on the revised sequence of assembly operations.
