CAM-I Scalable Flexible Manufacturing Initiative NGMS Task 6.1

2 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

3 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

4 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

11 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.

12 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)
