The production of these articles is based on well-established production processes, machines, and materials.
The aim of this unit is to introduce students to the application of a variety of material forming processes involved in the production of components and articles for everyday use. Among the topics included in this unit are: conventional machining, additive layer manufacturing (ALM), shaping and moulding processes used in the production of components, machine tooling, jigs and fixtures required to support the manufacture of components, using metallic and non-metallic materials such as polymers and composites.
On successful completion of this unit students will be able to describe moulding, shaping, and forging, ALM manufacturing processes, explain the importance of material selection, and summarise the impact machining processes have on the physical properties of a component.
