Web-based CAD/CAM for gear shaper cutters
New CAD/CAM system:
Benefits to the company:
Requires a lot of specialist knowledge and skillsNo specialised CAD software available in the marketDemanding flexibility in producing customised cutters
Flexibility in design
Better accuracy
Improved data transfer, storage & retrieval
Wastage reduction
Lead time reduction
Increase sales
Employs novel analytical model of gearingPlatform independent solutionEasy integration with the rest infrastructureUses open standards and softwareEasy to extend and maintainScalable and reliable

CUTTER
Design strategies:Entirely Web-based software systemParametric design visualisationArtificial intelligence elements for computationsModular 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 systemsWeb-based systems integrated with proprietary CAD toolsEntirely Web-based CAD systems
Web-based vs standalone systems:More managable and reliableBetter scalabilityPortabilityLess prone to crashing and creating technical problemsUsually cheaper to develop, deploy and maintainBetter data safety and availability from everywhereHigher level of abstraction from client platform
Utilised technologies:Python, TurboGears, PostgreSQL, JavaScript, MochiKit, ExtJS, SVG
