Index Requirements for Bare Cavities MIP/MTF Comments to the documents Example (HOM) Summary 2

3 Bare cavities Minimum requirements defined on the 1 st version of the specification (EDMS # ) Next Steps: Detailed design, Manufacturing and Testing Baseline documentation for each item/asset* to be provided at each stage Bare cavity *Item = a system part of a project Asset = a realization of an item. An item generates one or more assets (number of pieces to be produced)

Engineering Specification Requirements 4  MATERIAL AND FILLER METAL CERTIFICATES. TRACEABILITY SHEET  WPQR: Welding Procedure Qualification Record  WOPQ: Welding Operator Performance Qualification  WPS: Welding Procedures Specification  WELDING MAP & WELDING BOOK: Only identification for each weld to keep the traceability with WPS & tests performed.  MANUFACTURING PROCEDURES (Whenever required in our E.S Annex 6.3)  TEST PROCEDURES (Whenever required in our E.S Annex 6.3)  EB WELDED SAMPLES: CERN request a duplicate of every test coupon used for qualification purposes.  NDT PERSONNEL QUALIFICATIONS  MIP (Manufacturing & Inspection Plan): list of all manufacturing and quality control operations.  QC REPORTS generated after quality checkings

Manufacturing and Inspection Plan (MIP) Detailed Manufacturing Steps for Bare Cavities production Quality Controls to be performed during manufacturing 5 Follow-up the production Keep track of Inspections Records of verifications Identification of Deviations Further identification after installation

From MIP to MTF List of Quality Controls to be performed during the manufacturing process All QC Reports generated for each asset during the production will be stored in MTF (Repository of manufacturing data) Depends on the nature of the manufacturing step/quality control (Hold point or Notified point) the supplier can or can not continue with the next fabrication step 6 List of quality controls performed on the asset Step documents (control/test reports, NCR)

Review of actual document 7 This is the workflow for Bare Cavities Production not a Manufacturing and Inspection Plan Some steps of the workflow (fabrication or quality controls either) are not clear enough Lack of traceability between fabrication steps and the applicable drawings or referenced document Applicable standards to be followed as well as procedures need to be defined by supplier Manufacturing and Inspection Plan to be issued prior to manufacturing

Review of actual document 8

9 Example - HOM Couplers Visualizing the steps and the names makes it possible to anyone to easily follow the production steps

Example - HOM Couplers All Fabrication steps + All QC verifications are identified 2- Manufacturing and Inspection Plan (EDMS # ) Sequence of Quality Controls defined MTF Folder

Summary Workflow is a complementary document of the MIP but cannot replace it Traceability between the manufacturing or quality steps and reference drawings/documents Selection of Standards by supplier Definition of procedures by supplier 11
