A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a computer aided design (CAD) file processing portion, an inspection motion path generation portion and a user interface. The user interface includes a workpiece inspection program simulation portion and auxiliary collision avoidance volume creation elements. The workpiece inspection program simulation portion displays a 3D view and the auxiliary collision avoidance volume creation elements are operable to create or define auxiliary collision avoidance volumes that are displayed in the 3D view. In various implementations, rather than requiring a user to model a physical object (e.g., as part of a workpiece or CMM) in a CAD file, the user may instead create and position an auxiliary collision avoidance volume at a location where the physical object is expected to be, so as to prevent collisions that could occur with the physical object.

Systems and methods for generating a coordinate transformation are disclosed. The system can include a non-destructive imaging (NDI) device for detecting the location of local surface and subsurface features in an object (e.g., an aircraft). The system can compare the location of these local features to the location of features from engineering drawings (e.g., CAD files) to generate a coordinate transformation from a machine coordinate system, for example, to an absolute coordinate system. The system can then accurately locate a work piece to perform repairs or replacements, as necessary. The system can also include a robotic arm to enable repairs to be performed at reduced cost and with increased accuracy. The system can also compare two or more NDI scans to locate or relocate a machine that has been moved. This can enable the machine to be repositioned for repairs, maintenance, or to perform a two part repair.

A system and method for automated part inspection are provided. The method comprises receiving a corrective machine tool program comprising instructions for causing a Numerical Control machine tool to machine at least one finished surface of a part, the corrective machine tool program differing from a nominal machine tool program; determining from the machine tool program a desired position and a desired orientation of an inspection tool relative to the at least one finished surface; and generating an inspection tool path program defining a movement of the inspection tool relative to the part, the inspection tool path program comprising instructions for placing the inspection probe at the desired position and the desired orientation and acquiring at least one measurement of the at least one new finished surface.

A system includes an environment for programming workpiece inspection operations for a coordinate measurement machine (CMM). The environment includes a user interface comprising a program simulation portion configured to display a 3D view of the workpiece and/or representations of inspection operations to be performed on the workpiece. The user interface further includes auxiliary collision avoidance volume (CAV) creation elements that create CAV's that are represented in the 3D view. The 3D CAVs and/or their representations have integrated graphical modification properties which are controllable in the user interface. The modification properties are activated by selection of a face of the CAV representation, without the explicit activation of a separate modification control element mode or tool. This results in a simplified and intuitive user interface. Users perform a constrained set graphical modifications in the 3D view using an input device, to modify a CAV.

A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a computer-aided design (CAD) file processing portion and a user interface including a workpiece inspection program simulation portion, an editing user interface portion, and a simulation status and control portion. The simulation status and control portion is configured to respond to selection of workpiece features or inspection operation representations (e.g., as selected in the workpiece inspection program simulation portion or editing user interface portion). The simulation status and control portion response to the selection includes altering a simulation status portion (e.g., altering a numerical time representation or a position of a current time indicator) to characterize a state of progress through a current workpiece feature inspection plan corresponding to the portion of the current workpiece feature inspection plan directed to the selected workpiece feature or inspection operation representation.

A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a computer-aided design (CAD) file processing portion, a geometric relationship analyzer, an inspection motion path generation portion, and a user interface including an editable plan representation of a current workpiece feature inspection plan, a workpiece inspection program simulation portion configured to display a 3D view including geometric features and inspection operation representations, and a context sensitive menu portion. The context sensitive menu portion displays a context sensitive relational command menu that indicates a valid set of relational commands including relational feature or relational measurement commands operable to define a corresponding constructed feature or corresponding relational measurement operation to be included in the current workpiece feature inspection plan. The valid set of relational commands is determined based on a concurrently selected geometric feature set including at least two geometric features concurrently selected and indicated in the user interface.

There is provided a method for controlling a shape measuring apparatus which continues to perform nominal scanning measurement to a workpiece having a slightly large deviation from a design data. A scanning path to move a stylus tip is calculated based on design data of a workpiece. The stylus tip is moved along the scanning path. It is monitored whether a distance between the scanning path and an actual workpiece is excessive. When the distance between the scanning path and the actual workpiece is excessive, a trajectory difference error is generated. When the trajectory difference error is generated, geometric correction is performed to the design data so that the design data approaches to the actual workpiece. Scanning measurement is performed based on the design data after the geometric correction.

The invention relates to a measuring machine and a method for automated measurement of an object and detection of differences between a feature of the object and CAD data of the object. The measuring machine comprises a probe head, a probe system comprising a probe and measurement functionality for determining three-dimensional coordinates of a feature of the object, a local computer terminal, an assigned memory unit, and an assigned set of measurement software programs for controlling the measuring machine. The stored CAD data of the object comprise typical dimensions and tolerances of the features, and the assigned set of measurement software programs comprises an optimization algorithm for the measurement of each feature which algorithm is designed to automatically select measuring parameters of the measuring machine and/or a measurement software program from the set of measurement software programs.

A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine (CMM), including a user interface that comprises a workpiece inspection program simulation portion configurable to display a 3-D view of a workpiece; an editing user interface portion comprising an editable plan representation of a current workpiece feature inspection plan for the workpiece; and an editable alignment program plan representation for the workpiece. The system is configured with the editable alignment program plan representation being automatically responsive to editing operations, regardless of whether the editing operations are performed in the 3-D view or the editable plan representation. The editing operations include deleting or adding at least one workpiece feature to or from the editable alignment program plan representation.
