Automation (자동화) Associate Professor Su-Jin Kim School of Mechanical Engineering Gyeongsang National University 1

Manufacturing Automation Automation is the process of machines follow a predetermined sequence of operations with little or no human involvement. The major breakthrough in automation is numerical control (NC) of machine tools.

Hard Automation Machines designed to produce a standardized product, thus specialized and lack flexibility. Transfer mechanisms and transfer lines used to move workpiece from one station to another. High volume, High reliability, High production rates, High initial investment

Flexible Automation Programmable automation, Low production rates, medium quantity and varied production batches. Numerical Control (NC) is the controlling of the machine components movements by coding into the system.

Assembly systems 3 basic methods of assembly: manual, robotic , high-speed automatic. Manual Robotic Hard automatic Productivity Flexibility
