Methods and Tools in Screw compressor design
2
Overview of modern CAD systems
  • Integrated Computer Aided Engineering tools
  • Incorporate CAD, CAM, and other applications
  • User friendly icon based graphical user interfaces
  • Based on Variational/ Parametric technology
  • Encourage design flexibility and design reuse
  • Support Knowledge Based Design
  • Allow user applications to be inserted through programmable interface


3
Philosophy of modern CAD Systems
  • A Flexible Modelling environment
    • Ability to easily modify models, and implement design changes
    • Support for data sharing, and data reuse
  • Knowledge enabled
    • Capture of design constraints, and design intent as well as final model geometry
    • Management of non-geometric as well as geometric design information
  • The 3D Part is the Master Model
    • Drawings, Assemblies and Analyses are associative to the 3D parts.  If the part design changes, the downstream models with change too.
