the parts, they would have to be positioned securely. Moreover, handling sand cores


required additional constraints to ensure they were not worn or cracked during transport. Te fixture blocks were adapted to the sand core shapes to ensure enough rest area was available and they would be fixed properly on the pallet. In the tested automated pick-


and-place cell, various manual and motor-propelled jigs and fixtures rotated parts and assemblies through several axes and adjusted to the needs of numerous assemblers. Flexibility in the pallet fixture determined the degree of freedom available to part loading schedules. Tis flexibility also had to be taken into account when dealing with the ability to accommodate different parts of different shapes and sizes. As part of the Autocast Project, the aluminum casting facil- ity implemented four modular
