CAM-I Scalable Flexible Manufacturing Initiative NGMS Task 6.1
Vision • Our vision is E-manufacturing where we have • Seamless, scalable and robust evolution of products from design to manufacturing (and possibly to delivery and service) • Computer tools (such as simulators, rule-bases, visualizing environments) to rapidly plan, validate and deploy manufacturing instructions • Flexible manufacturing systems for simultaneous production of multiple products and minimum system change over
Broad Goals • Manufacturing evaluation and deployment of emerging standards (STEP 203 and 210, possibly 220) • Development of environments for manufacturability analysis of designs • Manufacturing process planning and simulation environments • Simulation and control for flexible manufacturing of board assemblies
Immediate Goals • Implementation of visualization and translation tools for STEP AP210 (Generate 3-D models of assembly from AP210 descriptions) • Computer implementation of Rockwell’s DFM rule base to function with AP210 description of boards • Simulators for placement processes and machines (HSP and GSM simulators) • Development of capabilities to ‘virtually’ produce a board (AP210 ‘as produced’ view of board assembly) • Generation of (HSP) machine input files from AP210 model

Why STEP? • Emerging standard • Million seats of AP-203 presently deployed • Simulation tool to be used across manufacturing facilities and vendors • e-manufacturing • E-Business applications of STEP are being enabled by the STEP and W3C committees working together.
What is STEP? • ISO standard (ISO 10303): • to share and exchange digital technical information • Set of common data structures • Application Protocols - Domain specific usage of data structures • AP 203 (3D solid Models)
AP210: Electronic Assembly,Interconnect and Packaging Design Product Structure/ Part Connectivity • Functionality • Analysis Support • Shape 2D, 3D • Package • Material Product • Properties • Functional • Packaged Physical • Component Placement • Bare Board Design • Layout templates • Layers non-planar, • conductive & non-conductive • Material product Configuration Mgmt • Identification • Authority • Effectivity • Control • Requirement Traceability • Analytical Model • Document References Geometry • Geometrically Bounded 2-D • Wireframe with Topology • Surfaces • Advanced BREP Solids • Constructive Solid Geometry Requirements • Design • Allocation • Constraints • Interface • Rules Design Control Technology • Geometric Dimensioning and Tolerancing • Fabrication Design Rules • Product Design Rules
AP 210 • Several product models in electromechanical domain. • Supports Multidisciplinary library data. • Scope is “as required” & “as designed” product information. • Sharing across several levels of supply base. • Ability to Integrate with other engineering domains. • Ability to integrate external services coherently.

2D to 3D converter • ECAD translators generate AP 210 files containing 2D Geometry • Simulate 3D view of the assembly board • Converter • Input : AP 210 file (2D geometry) • Extrudes them into solids (Advanced BREP) • Output: • AP 210 file (2D + 3D geometry) • AP 203 files
2D to 3D converter • Ap203 files • Individual packages • Board • These files then converted into Open Inventor format • Inventor: Graphics package used for rendering
Schema User Interface Rule Execution Software Rule Definition Software DFM • We are adapting a system originally developed by Boeing for use at Rockwell • Developed on PreAMP and TIGER project. • RDF syntax • Inputs • AP-210 Design File • Rule Files • Configuration Management
DFM Rule Facility • Subset of Rockwell Collins DFM rules were chosen for implementation. • Relevant facts extracted from the AP-210 file during preprocessing. • Rule Inference engine insulated from intricacies of STEP • Different facilities can easily plug in their DFM modules. • Interface to the simulator • DFM rules which were violated • Components which violated these rules.
Assembly Data • Establish an assembly usage view • Components • Organization by package / part family • Part numbers, version • Configuration management data • Location, orientation • Reference Designators • Integrated with OPTEL • Magazine Setup • Optimized placement sequence
