Metrology Assisted Assembly & Automated Inspection - Leica ...

In this case it would be possible to replace the userinterface completely as seen in the visualbasic examplein section 3.2. PC-DMIS becomes the “brains” of themeasurement process controlling the import & exportof data, all measurement commands, bundle & alignmentmathematics, and complete database control. TheStep 1: Initialize Measurement ProcessStep 2: Read in Nominal from DatabaseStep 3: Measure Reference PointsStep 4: Bundle StationsStep 5: Align Stations Setup to FuselageStep 6: Measure Actual Wing PositionStep 7: Measure T-Mac PositionStep 8: Determince T-Mac TransformationStep 9: Measure T-Mac Position Calc deviation of actual Datum Point positionYesAbove specified Safety GapHuman Machine Interface can then be completely customizedbased on the needs of the automation projectwith a simple program that no longer needs to worryabout the actual metrology processes.We can use the Leica Geosystems 6DoF MAP systemas an example of how PC-DMIS could be used as aMeasurement Process Manager independent of the HumanMachine Interface, or the final reporting database.The workflow assembly process could look as follows,where PC-DMIS would be responsible for steps 1 – 9below. Here the 3rd party integrators Human MachineInterface only needs call step 1, and then PC-DMIScould take over the automation through step 9 until theAssembly Process Manager becomes involved to reactivatethe measurement process after the jig has moved.This loop would continue until step 11 when PC-DMISwould then send the completed measurement resultsto a global database storing the wings final location.At this point the Human Machine Interface would thenbecome integral in detailing the next steps, or statingthe process over again.Send Deviations toAssembly ProcessStep 10: Measure automated all Datum Pointson WingYesRe-measure PointsStep 11: Measure final position of DatumTransfer Points on Wing Re-measureWhite results toDatabase10 Application Specific Measurement Processes
