‘COOL RIM’ – Cavity Trim PartStep 3: Cavity Trim Part
Vertical wave link to casting model
Apply shrinkage factor for cast material (scale feature)
Extracted cavity regions – along parting line divisions
Tooling seal-off faces developed and attached to appropriate cavity regions to form unique cavity trimming tools

What is important for successful design?
File organization: keep it simple and straightforward
Proper and efficient use of modeling techniques
Efficient WAVE management

GOOD Design Practices
Layer structure / category naming File Organization:
Modeling tree structure –feature sequence/grouping/naming
Expression/formula definitionDefined geometry reference sets

GOOD Design Practices
Fixed datums and primitives: as startup features onlyModeling Techniques:
Don’t be afraid of using sketches: avoid using non-parametric “flying” wireframe

GOOD Design Practices
Fixed datums and primitives: as startup features onlyModeling Techniques:
Don’t multiply features: especially datumsDon’t patch model by adding features over existing onesDon’t build deep model dependenciesAlways check validity of model geometry
Don’t be afraid of using sketches: avoid using non-parametric “flying” wireframe

GOOD Design Practices
Upfront planning investment into model and file organization and diligence in keeping model files “clean & lean” will bring multiple benefits to seamless flow of design information
CADmech Design Inc. Your success; there is no compromise

WAVE Management
Efficient WAVE management without WAVE Control License
Vertical (serial) WAVE linking
Horizontal (parallel) WAVE linking
Managing WAVE links - breaking, reattaching, updating links
CADmech Design Inc. Your success; there is no compromise

WAVE Geometry Linker – What are the benefits?
Full parametric integration of part design data into tooling design process
Flexible management of linking process
“Geometry safe” method
Improved performance (smaller individual files)
No additional license required
Helps even with “challenging part geometry”

Problem Geometry – How to deal with it?
Well defined and simplified parting lines
With clean part geometry, even non-parametric data integration can proceed
WAVE management is critical to preserve tooling data integrity – breaking and re-establishing WAVE links, delayed updates
Topology problems must be fixed – clean topology is aMUST for math data integrity
