Vision
Our vision is E-manufacturing where we haveSeamless, 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 standardMillion 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.

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.
