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. Automation and CIM Manufacturing Processes © Pearson & GNU Su-Jin Kim

Hard Automation (고정자동화) • • • 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 Automation and CIM Manufacturing Processes © Pearson & GNU Su-Jin Kim
