ROYAL CANADIAN MINT’S VISION
2
The value we add to Canada and to
Canadians
Our customerdriven
businesses
Our talented people
The Mint’s vision is dedicated to delivering excellence … through
R&D FOCUS
3
Speed to MarketCoins with unique shapes, sizes and
relief
Reduced Cost
SOLUTION� Finite Element Analysis (FEA) to “virtually strike” c oins
� What is FEA?
� Keys to success for applying FEA @ the RCM
4
Input
- Tooling and blank shape- Boundary conditions- Material properties - Interaction properties
Virtual Striking using FEA
Output
- Virtual coins- Stresses/Strains- Striking force- Unfilled areas
