1. Exemple de mise en place d’une méthodologie: Les ensembles mécano-soudésSTATUT le 22 .03. 2012 R. Betemps / EDMS Doc N° 1207628

2. Topics • Why « Mecanosoude» as first subject. • Main requirement. • Actuel Propositions. • Example / link in Smarteam. • Conclusion. • Next step. • Questions / Comment. R. Betemps / EDMS Doc N° 1207628

3. Why « Mécanosoude» as first subject • This subject concerns many people and different departments. • This design type is use daily at Cern. • This subject will “open” general questions of methodology. • A first job has been already done and presented by Luca Gentini. R. Betemps / EDMS Doc N° 1207628

4. Description of «Mécano Soude» • Welded frame with machining R. Betemps / EDMS Doc N° 1207628

5. Main requirement • Describe a methodology to design welded frame and deliver manufacture documents. • Use this methodology for 80 % for of the welded frame. • Ensure the coordination with the other projects GrACQ, PLM-WG. • Ensure the documents quality for different departments Method, machining … • Users friendly. R. Betemps / EDMS Doc N° 1207628

6. Remember: design Process Save the different drawing status Deliver: manufacture drawings with all the different manufacture steps Deliver: functional drawings with functional dimensions Deliver: Effective parts R. Betemps / EDMS Doc N° 1207628

7. Actual propositions 1. Use: Assembly with parts to make the models. (No multi-bodies) • More work for the design office but more flexibility globally Better solution on the complete process. (Cf Example). 2. The two structures DO and MO should be independent (Catia). 3. A status of the drawing (release) have to be identified before starting the production on the Workshop. 4. The design 3D coming from the DO should be compared with the design coming from the MO (geometries should match). 5. All the dimensions are on the drawings (no dimensions on the part list). 6. All material information should be present. 7. Create a Link in Smarteam between the Model of the design office(DO) and the method drawing (MO). 8. On the method drawings(MO) the drawing N° of reference DO drawing should be present. R. Betemps / EDMS Doc N° 1207628

8. Example Design Office (DO) 1 assembly with 3 Parts. 1 Drawing. Catia / Smarteam Structure R. Betemps / EDMS Doc N° 1207628

9. Example Method Office (MO) Some intermediary Steps have to be made to manufacture the final parts: • Part 1: should be done inseveral steps: • Machining. • Annealed. • Machining • Weld with the other parts. • Part 2: Should be done in several steps: • Weld with the other parts. • Machining. • Part 3: Should be done in several steps: • Weld with the other parts. • Machining. R. Betemps / EDMS Doc N° 1207628

10. Example Catia / Smarteam Structure Part with several step Sub-assembly semi-finished Final part R. Betemps / EDMS Doc N° 1207628

11. Link in Smarteam: Propositions With Specific “Document type” With Specific “Document type” R. Betemps / EDMS Doc N° 1207628

12. Explanation • A specific “document type” should be created to distinguish the different documents. • The tool “BOM Compare” should identify this difference. Development R. Betemps / EDMS Doc N° 1207628

13. Conclusion • All these proposals are made to be as simple as possible. • These proposals will set a direction for other methodologies. • We tried to take into account the next steps for other groups: GracQ, PLM-WG. R. Betemps / EDMS Doc N° 1207628

14. Next Step • Collect all the comments and remarks on these proposals. • Include discussions on specifics cases. • Writtingof a final document. • Start to use it. R. Betemps / EDMS Doc N° 1207628
