Manufacturing Processes - MFRG 317 - Home Page

1. Introduction
This module will continue and complement the previous studies, covering a number of manufacturing processes. The emphasis is mainly upon metals but plastics are also considered.

2. Assessment
Assessment will be by a combination of course work (30%) and examination (70%).

3. Processes

Principles of Metal deformation

3.1 Forming Processes

Material Properties - laws governing metal flow

Stress - Strain Curves

Work and Efficiency in Metal Forming

Friction

Redundant Work and 3.2.6 Relationship Between Hardness and UTS

.....Plane strain yielding
.....Axisymmetric compression of a cylinder applet
.....Relationship between coefficient of friction and frictional shear factor
The main processes can be grouped under the following headings:
3.4.1 Forging
3.4.2 Rolling, example on cold rolling: Page 1, Page 2, Page 3
3.4.3 Extrusion and 4 Drawing
3.4.4b Wire drawing: Pressure on the die and axisymmetric yielding
3.4.5 Sheet metal processes
