Palette system

Hi All, I am Diploma Engineer from Bulgaria. Conclude Machinery and Technology. I decided to design a thesis on "fast companies establishing details on machined" by pallet mechanism. I decided to share this with readers to be able to discuss, which method gives greater accuracy and speed when changing palette mehanism.
Can you tell, what do you think is the most suitable method? Later I will share with you photos of my almost finished thesis, especially for milling machine "Rais 500" with FANUC control.
