MEEN20020 Manufacturing Engineering I

Academic Year 2022/2023

This module introduces the field of manufacturing engineering, where the following topics constitute the syllabus:
- Relationship between design, materials and manufacturing;
- Introduction to engineering materials; primary and secondary processing of metals; trends in manufacturing e.g. Industry 4.0;
- Forming of metals: plasticity and work hardening; temperature effects; hot and cold forming; grain structures; recrystallisation; annealing; analysis of sheet rolling, wire drawing, and extrusion processes; characteristics/design of rolling mills;
- Casting of metal alloys: casting methods e.g. sand casting, investment casting, permanent mould casting; influence of fluid flow and heat transfer in casting; microstructure and grain growth; alloy phase diagrams;
- Subtractive manufacturing: mechanics of machining; machine tools and their automation; cutting tools and cutting tool materials; tool behaviour and tool life; non-traditional machining processes e.g. electrical discharge machining;
- Moulding & forming of polymers;
- Computer Aided Design and Manufacturing; history of Computer Numerical Control; G-code; capabilities of machining centres;
- Additive manufacturing technologies: introduction to 3-D printing; fusion deposition modelling; selective laser sintering; stereolithography; laminated-object manufacturing;
- Joining methods: welding methods e.g. fusion (oxyfuel gas, shielded metal-arc, gas metal-arc, gas tungsten-arc), solid-state (spot/resistance, friction), brazing, and soldering; heat-affected zone of welded joints; residual stresses of welded joints; adhesive bonding; mechanical fastening;
- Surface engineering: metrology; plasma treatment; physical vapour and chemical vapour deposition; contact angle measurement; optical microscope, micro-hardness tests;
- Economics of production: process design and analysis; competitiveness and productivity in production.

The lecture sessions, providing the theory and analysis of manufacturing methods, are complemented by four laboratory sessions (participation deemed compulsory), providing the student with a hands-on experience of manufacturing methods, and a requirement to demonstrate a knowledge of the health & safety procedures associated with manufacturing processes.

The four laboratory sessions are undertaken in groups, and with due regard to the School's Health & Safety protocols. Students are obliged to comply with these (see https://intranet.ucd.ie/smme/index.html) during their laboratory activities. This includes wearing a laboratory coat.

The online discussion forums (fora) will require students to communicate to their peers using online media, which will be evaluated as part of the overall assessment for this module.

Learning Outcomes:

At the completion of the module, the students should be able to:
1) Explain the relationship between design, materials and manufacturing, and describe the trends in manufacturing;
2) Describe traditional manufacturing processes for metals (e.g. casting, forming, machining) and polymers and discuss their relative merits;
3) Describe appropriate methods for materials processing, joining and surface engineering;
4) Appreciate the influence of microstructure on material performance and show examples of ways in which the microstructure is influenced by processing;
5) Explain the concepts of additive manufacturing and discuss its merits relative to traditional manufacturing processes;
6) Analyse the efficiency and productivity of manufacturing processes.
