Boxyor… I wouldn´t done it that way
Magnus Lundgren magnus.lundgren@iip.kth.se B.Sc., Ph.D Student KTH, Royal Institute of Technology Computer System for Design and Manufacturing Machinist background Has worked as CNC-operator and manufacturing engineer for about 10 years before entering studies at KTH. Graduated for B.Sc. in 2001 and after that working with education at KTH in the area of manufacturing engineering.
Parksville, May 2009 • Multiple setups • Multiple CAM systems • Metric part and tooling • Machining tests from 2009-07-15 to 2009-09-15 • KTH (Tricept & Mazak VQC) • Scania (Hardinge VMC 600 II) • Boeing (Okuma, Northwood) • University of Bath (DMG?)

Feature, Mfg. Tolerances, Processes and Resources (machine tool, cutting tool, fixture etc), Capability? (ability to produce within an specified tolerance), Manufacturing feedback in a context, which machine tool, which cutting tool, which fixture, what kind of feature, etc,.
Results and conclusions • The ability to insert workplans and reorganize workingsteps worked very well and allowed us to adapt a master process for different machine configuration • 3-Axis machining in 6 setups • 3-Axis machining in 12 setups (more robust process) • 4-Axis machining in 2 setups • 5-axis machining in 2 setups • Being able to also add/replace workingsteps, e.g. already existing WS from another project or new ones created in a CAM-system, i.e. CAM to CAM would be a useful improvement and perhaps a suitable challenge for next demo.
