Overview:

This module covers the process of engineering design, manufacturing methods, and the relationship between them. It builds on the introductory material covered in MECH0004 Mechanical Engineering Practical Skills and MECH0007 Fundamentals of Materials.

The module aims to train students in the methodology of all stages of engineering design: from the analysis of the client statement to the manufacturing of the design. It develops the practical, theoretical, and computational engineering skills relevant to the design process. It also aims to develop an appreciation of sustainability in engineering design, and an understanding of how design decisions can affect the environmental and economic costs of the design and product.
