Presentation Transcript

  1. Overview • Review ISPE tasks • Process areas • Implementation approach • AP218 Units of Functionality subset • Schedule • Other issues

  2. Steel Processing - ISPE Overview • General Objectives • Enable efficient partnering among yards • Decouple CAM from CAD • ISPE Implementation Concept • Utilize a STEP-based CAD/CAM data exchange • Expose all manufacturing requirements and rules • Accumulate manufacturing information using neutral design and yard processes • Use ISPE as the CAM “front-end”

  3. Shop Planning Shipyard Proc Mfg Rules Steel Processing - ISPE Overview Phase 1 Phase 2 ISE Steel Proc. Adjust for Weld Shrinkage Define Edge Preparation Part Generation Create Manufac-turing Aids Reports and Drawings CATIA v4 export ISPE Repository Simulation AP218 Validation Manufactur-ing Data CATIA v5 export AP218 (Ship Structures) AP218 AP238 (STEP-NC) Config Mgt Robotic Welding Tribon export Nesting AP216 (Ship Molded Forms) Intergraph export Manufactur-ability Analysis MRP Interface

  4. From ISPE Phase 0 ConOps

  5. Process Areas • Automate the creation of manufacturing product model • Relates to manufacturing engineering • Affected data: • e.g., weld shrinkage/fit-up allowances, part generation, etc. • Automate the application of yard/shop specific processes • Relates to work share/internal routing • Affected data: • e.g., part edge definition, weld process, labels, fabrication, etc. • Collaboration/Change Management environment

  6. Recommended Approach • Identify target systems • What data within 218 is required? • Identify Representative data set • Export from ISDP • One that highlights work sharing issues • Is there any information to add/modify that would help the conversion to 238? • Determine the current process, used within target yards, to convert the data • Use this process, and the underlying required information, to influence the Mfg Rule/Process schema • Identify attributes/constructs with AP 218 (216?) that are yard/shop dependent

  7. Units of Functionality • definitions • product_structures • ship_manufacturing_definitions • structural_features • structural_parts • welds

  8. Application Objects • manufacturing_definition • assembly_manufacturing_definition (assembly_method, assembly_stage) • structural_part_manufacturing_definition • weld_manufacturing_definition • item_structure • item_relationship • feature_relationship, • structural_feature_relationship • part_relationship • structural_part_relationship • plate_relationship • plate_boundary_relationship • profile_relationship • system_relationship, structural_system_penetration_relationship, structural_part_penetration_relationship, assembly_relationship • structural_part_joint • structural_part_connection_implemenation • structural_feature • structural_manufacturing_feature • feature_design_definition • corner_cutout_design_definition • bevel_design_definition • shear_bevel_design_definition • structural_part_joint_design_definition
