High Speed Trains
•Desktop sized Factory •Build small parts with a small factory •Greatly reduces space, energy, and materials
Mechatronics Systems-Manufacturing Applications-
Micro FactoryMicro Factory Drilling Unit
CNC Bending•Fully automated bending: load sheet metal and the finished bent parts come out•Can bend complex shapes
Mechatronics Systems-Manufacturing Applications-
•Train Position and Velocity constantly monitored from main command center. •Error margin in scheduling no more than 30 seconds•Fastest trains use magnetic levitation

AUTO-CAD INTERFACE.....
Produced very quickly.modified very easily.Easily add colour & surface
texture.Test structural designs
before building eg: bridges & skyscrapers.
Easily sent by emailLess storage space required
than a ‘real’ model.Create realistic simulations.Clients can explore virtual
‘walk through’ of 3D model designs.
ADVANTAGES
Lack the feel of a traditional model.
Cost of computers and software.
Training of staff in use of software.
Maintenance of IT systems & network servers.
DISADVANTAGES....
PARAMETRIC MODELING
Introduction to Solid Modeling
3D COMPUTER MODELS......
Development of 3D modelling software enables architects
Create realistic 3D models of their designs
FEA...
How do you control color and appearance.
Assign Materials. Assign Shaders. Assign Textures. Advanced Shaders – eg Renderman.
