7 Capvidia Technical Presentation Ensuring 3D CAD Data Quality in Engineering Processes Complete & Accurate 3D CAD Data Exchange and Validation Data Exchange: Example between Boeing and Supplier chain Precise CAD Data Translation D Quality Assurance Standard For Digital Product Definition at Boeing Suppliers Data Validation Validation Processes implemented at Boeing CompareVidia - Data Validation Solution from CAPVIDIA Tracking of Engineering Changes PMI validation Questions & Answers

8 CAD data exchange Model Based Definition 3D CAD model + Metadata CAP-XML (DMSC QIF/PDPMI) Geometry Topology PMI (GD&T, FT&A) Attributes Solid/B-REP Model Based Definition

9 CAD data exchange Current CAD data formats have many overlaps and still a lot of gaps. Gaps CAD Format A CAD Format B Overlap

10 CAD data integrity Processes where CAD Data Integrity is a requirement and not an option? Manufacturing Metrology Long Term Archiving Simulation (FEA, CFD, etc)

11 Why CAD data validation? CAD data validation to meet ISO 9001 quality standards to comply with MBE enterprise requirements to comply with e.g. Boeing D recommendation

12 Why CAD data validation? Authority CAD Data CAD Translation Derivative CAD Data CAD Validation

13 Validation Process Imported CAD model CAD Validation Validated reference model First Touch Validation (Based on use of reference data) Reference Model Validation (Boeing D based on authority model) First Touch Validation Global characteristics Number and type of entities Bounding boxes Reference points STEP AP 242 Other standards Reference Model Validation Authority model Geometry Topology PMI Attributes Boeing D

14 MBD based Manufacturing - validation Boeing D Validation criteria CAD translation Criteria: Geometric model correspondence Parameters tolerance validation direction authority -> check check -> authority check -> <- authority

15 Boeing D Data Validation Original Model Given to Supplier CompareVidia Authority Model Compare Passed/Failed Check Model Report XML,HTML, PDF Imported to Supplier CAD/CAM/CMM/CAI System (MasterCam, SurfCam, SolidWorks, etc) Exported from Supplier CAD/CAM/CMM/CAI System (IGES, STEP or CMM Points)

16 Results Easy to Understand Compare Tree Color Scale Deviation List

17 Process documentation 2D Report (PDF, HTML, TXT, XML) 3D Report (XML, 3DPDF)

18 Extended Validation Criteria Validation of 3D geometry (D ) is not enough 13 surfaces 226 surfaces 226 surfaces CATIA V4 CATIA V5 STEP Authority Model Derivative Model 1 Derivative Model 2 Topology is lost in the translation process

19 MBD based validation topology Authority Model CATIA V4 Check Model CATIA V5 Geometry + topology based validation, tolerance inch

20 Boeing supplier example

21 Boeing supplier example SURFACE ROUGHNESS - Ra Geometry validation is Passed Validation criteria were ONLY based on geometry Final product was rejected by Boeing due to unsatisfactory surface roughness

23 Boeing supplier example Validation passes based on geometric criteria

25 Boeing supplier example 74 Surfaces 53 Surfaces Validation failed based on topology criteria

26 Boeing supplier example Validation fails due to surface explosion (detected by adding topology to validation criteria) It is the same surface where CNC had a problem

27 Topology change -> NC Tool path change Tool path direction No surface explosion Tool path direction changed Surface explosion Ra < Ra Smooth Raw

28 Boeing supplier example Accurate translation (taking topology into account) result Before After

29 Metrology Challenges: Data Transfer including support of full CAD metadata: PMI (Product Manufacturing Information) GD&T (Geometric Dimensioning & Tolerancing) FT&A (Functional Tolerancing and Annotation) 3D CAD data with related GD&T information can be transferred between applications in complete & consistent form using open XML DMSC PDPMI data format supported in Capvidia products (Capvidia is a DMSC member and contributor in definition of the open XML based PDPMI data format) Data Validation complete & accurate data GD&T validation: Based on GD&T representation data (but not on GD&T presentation) and the shape of a product in some useful format (e.g. a boundary representation), it is possible to validate the completeness and consistency of the GD&T information. The software tool FBTol from the Kansas City Plant is probably the first one in this area.

30 Long Term Archiving Challenges: Choice of data Format (STEP vs. XML) Open & compatible with wide range of applications Standard STEP AP 242 Archiving time exits 50 years in aerospace industry (aircraft operation life-span) Legal obligation FAA regulation Validation of data Quality prior to archiving Use of quality standards VDA-4955, SASIG, AIAG D15, JAMA, etc. Use of internal standards defined by process requirements The objective of LOTAR International is to develop standards for long-term archiving (LTA) of digital data, such as 3D CAD and PDM data. These standards will define auditable archiving and retrieval processes. The documents for the standard are published as the EN9300 series and, in cooperation with the AIA, also as the National Aerospace Standard (NAS). The LOTAR project consortium consists of user companies from around the world. Member companies include Airbus, BAE Systems, Boeing, Dassault Aviation, EADS, Eurocopter, General Dynamics, Goodrich, IAI, Lockheed Martin, SAFRAN, Sandia, and Spirit.

31 CAD Data Quality Assessment

32 Quality Assessment MIL-STD Check 3D model quality against DoD MIL-STD

33 CAD Quality Data of Quality an Authority Assessment Model -example Identified small entities will be lost in data translation causing Check Model to fail validation against Authority Model Authority model Export Tolerance inch Check Model Import Tolerance inch Length of the tiny surface edge = [inch] This surface will be lost in Check Model

34 CAD Data Quality Assessment Customer Carden Machine Workflow Authority Model CATIA V5 STEP Check Model MasterCAM STEP Validation Tolerance [inch] Authority model Check Model Validation Failed
