Care & Feeding of Machines
• Feeding parts– vibratory feed bowls– conveyors– pick & place
• Material obtained from:– Boothroyd, Automatic Assembly– Ken Goldberg, UCB Industrial Engr Oper. Rsrch

Fastener Feeding Requirements
• Orientation– vibrating bowl– non-vibrating feeders
• (see Boothroyd - Assembly Automation)
• Singulation– escapement mechanisms– pick and place
• Pre-collated components
