School | Cardiff School of Engineering |
Department Code | ENGIN |
Module Code | ENT604 |
External Subject Code | 100202 |
Number of Credits | 10 |
Level | L7 |
Language of Delivery | English |
Module Leader | Dr Michael Packianather |
Semester | Autumn Semester |
Academic Year | 2025/6 |
Outline Description of Module
- To review requirements of measuring instruments and processes which include process foundation and process-setting.
- To acquire knowledge of the principles of general metrology and their standards including the software used in measuring instruments and systems.
- To acquire an understanding of the principles underpinning the design and operation of metrology systems including coordinate measurement machines, comparators and ball bars.
- The application and practice of product development using reverse engineering.
On completion of the module a student should be able to
- Appreciate today’s technologies to transform manufacturing performance through metrology.
- Be aware of the techniques, equipment and instrumentation that may be used.
- Understand the mechanisms that are available to increase throughput, reduce waste and incorporate traceability.
How the module will be delivered
A number of industrial Case Studies are structured within the module to illustrate some of the key themes. These case studies reflect both documented evidence and experience of current research activity of the academic staff associated with the module. In particular in the Renishaw Metrology Lab, which houses state-of-the-art facilities, will be the base for the coursework element of this module. In this way students gain a better understanding of some of the many issues associated with this broad-based subject.
The module will be delivered through a blend of online teaching and learning material, guided study, and on-campus face-to-face classes (tutorials, lab sessions). Structured problems are also integrated within the module notes and students are encouraged to discuss their solutions within the class tutorial environment. Where appropriate, demonstrations are used to aid understanding. This strengthening of knowledge in each module theme will help students towards meeting the learning outcomes.
Skills that will be practised and developed
- Carry out measurements at a given accuracy level, and perform statistical calculations resulting from several measurements in control by sampling, and deduce the correct conclusions.
- Interpret information from a range of sensors and techniques.
- Carry out calibrations while taking account of external conditions and of the level of accuracy required.
How the module will be assessed
This module is assessed using two components, which are weighted as follows:-
(1) Two-hour written examination 80%
(2) Laboratory / Coursework 20%
In order to pass the module and obtain 10 credits, the minimum pass mark of 50% must be achieved in items (1) and (2) combined.
There is a potential for re-assessment in this module which may result in a 100% written assessment during the August Resit period.
