THE WIND FISH: CNC FISH WHISTLE

Processes: CNC Machining & CAM, DFM/DFA, Lateral Thinking, Rapid Prototyping

Project Brief

In 3 weeks, design an assembly of parts that:

  • involves at least one part flip

Also, learn how to create and debug a molding program

Challenges

  • Modeling a semi-organic form in CAD

  • Determining the best gate location to minimize number of sink areas and sink depth

Results

A very hard-earned success that seemed at first unattainable!

  • The duck body is charmingly rotund and has no visible sink thanks to insert- and overmolding strategies

  • Statistical analysis proved extremely effective in ensuring that shrunken parts fit in the mold with no gaps during overmolding and fit perfectly together

  • Enhanced confidence in CAD, CAM, and molding
