7. Manufacturing Automation Technology
Trinity College Dublin, The University of Dublin
Machine attachments
❑Oldest automation technology and simple automation
❑Add-ons to machines or production lines
❑Perform one or a few simple actions
❑Less intelligent (not programmable)
❑Simple design and configuration
❑Relatively low cost and wide variety
❑Widely used in today’s industry

8. Manufacturing Automation Technology
Trinity College Dublin, The University of Dublin
Grasping,loading and capping machines

9. Numerically controlled machines
Trinity College Dublin, The University of Dublin
CNC milling machine

10. Numerically Controlled Machines
❑Computer control and programmable
❑Read instructions and translates them into machine
operations
❑Combine computer and conventional machine tools
❑Widely used in manufacturing workshop to make
parts with complex structures.
❑CNC – computer numerically controlled
❑DNC – direct numerically controlled (several
machines controlled by a single computer)
Numerically controlled machines
Trinity College Dublin, The University of Dublin

11. Numerically controlled machines

13. Industrial robots
Trinity College Dublin, The University of Dublin
Industrial Robots
❑Computer control and programmable
❑Read instructions and take action
❑Human-like machines and do human jobs
❑Can replace human labour (welding, assembly, etc.)
❑Can operate in environments hostile to human (Fukushima
in Japan,fireground,warzone)
❑More precise than human action
❑Work repeatedly without fatigue
❑Have sensors (proximity, vision, tactile) to prevent damage

14. Industrial robots
Trinity College Dublin, The University of Dublin
Universal industrial robot

15. Industrial robots
Trinity College Dublin, The University of Dublin
“Dancing” Robot

16. Automated Quality Control Inspection
Trinity College Dublin, The University of Dublin
Automated Quality Control Inspection
❑Photographic (2D) or CT scanning (3D) units
❑Computer control and analysis
✓Take physical features of parts
✓Compare measurements to standards
✓Determine if parts conform to specifications
❑Automated rejection system
❑Replace human with much higher efficiency, higher
accuracy and less mistakes

19. Automated Identification Systems
Trinity College Dublin, The University of Dublin
Automated Identification Systems
❑Camera, sensor, scanner, radio receiver for identification
❑Optical character, magnetic stripes, bar codes, radio
frequencies
❑Data read from products, documents, parts, and containers
❑Computer control and analysis
✓Reading information from the input
✓Analysis, make decision and, operation
❑Replace human with much higher efficiency and accuracy
❑Mostly used in retail, postal,express services.

23. Automated Process Controls
Trinity College Dublin, The University of Dublin
Automated Process Controls
❑Mostly used in petroleum or chemical industry
❑Sensors to monitor and measure ‘dynamic’ process
variables (e.g., temperature, pressure, flow rate).
❑Computer control and analysis
✓Analysing the measurements in real-time.
✓Make decisions if necessary (e.g., open valves,
slow down pumps, turn on heaters)
❑Take actions
❑Replace human with more safety, continuous monitor,
higher precise, higher efficiency.
