School of Mechanical Engineering
Gyeongsang National University 1

2. 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.

3. 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

4. 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.

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

6. Programmable Logic Controller (PLC)
PLC is a digital computer used for automation of electromechanical processes
