CUTTER
Design strategies:
Entirely Web-based software system
Parametric design visualisation
Artificial intelligence elements for computations
Modular user interface
Project aim:
To develop and implement a
CAD/CAM system for gear
cutting tool design and
manufacture exploiting state
of the art hardware and
software technologies
Gear cutting tool design & manufacture:
Networked CAD classification:
Distributed CAD systems
Web-based systems integrated with proprietary CAD tools
Entirely Web-based CAD systems
Web-based vs standalone systems:
More managable and reliable
Better scalability
Portability
Less prone to crashing and creating technical problems
Usually cheaper to develop, deploy and maintain
Better data safety and availability from everywhere
Higher level of abstraction from client platform
Utilised technologies:
Python, TurboGears, PostgreSQL,
JavaScript, MochiKit, ExtJS, SVG
Duration: 2007 - 09
