ACF  Aligned CFrame
ACF is a
new type of Cframe(tool holder) for different types of joining
applications such as self piercing riveting(SPR) and clinching. The
lightweight aligned Cframe (ACF) increases mobility and productivity and is
well suited for automated processes.The ACF
is designed using a combination of modern finite element
structural optimisation. Below an example of a conventionel
Cframe is showed together with an illustration of different occuring process errors

Optimisation of an ACF 
First step is formulate the optimisation problem,
i.e which objective, constraints and design space we have to deal
with. 
Initial FE model, deformations amplified x10 
Optimisation formulation

Definition phase
1. Include analysis 
2. Define design variables 
3. Define objective function 
4. Define constraints 
The mesh morphing
phase
Import model to the morpher 
Create morphing geometry (grey) 
Add design varibles to morphing geometry and link to nodes 
Testing, some selected variables varies between it's limits 
Solution
phase
Start executions 
and follow how the optimisation proceeds 
Postprocessing phase
