Paper Description

Edit Paper Description Content

This paper will furnish the student with a knowledge of modern manufacturing processes (not necessarily all of them directly related to building a working prototype machine) and how to use them when designing complex machines. The paper builds on the material taught in ENGME280 Design and Manufacturing 1. The paper will require elements taught in ENGME280 to be used in ENGME380. Dirty prototyping will be taught and applied to a design project. Students will be required to apply modern manufacturing methods such as laser cutting, CNC machining, and 3D printing to the design of a complex machine. Students will undertake a group design project and build a working prototype machine that meets a specification.

Paper Structure

Edit Paper Structure Content

This paper is taught with lectures on design and advanced manufacturing processes, plus two x two hour labs each week for the design project. Case studies from design engineers will be part of the design lectures. Students work in groups of two or three to complete a Project Based Learning (PBL) design, build, test project. The project enables students to apply ENGME380 material and that from other Mechanical Engineering papers, to develop a fully functioning prototype to meet a given design specification. Other material, such as manufacturing techniques, is assessed by three tests.

Assessment

Edit Assessments Content

The assessment of this paper comprises one group design project and three manufacturing tests. The design project has been split into 5 parts: concepts, CAD, manufacture & cost, efficiency & health and safety, machine performance. Details of the design project are given on a separate assignment sheet.
