Characterisation and modelling of electro-pneumatic production systems
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Compressed air is a widely employed energy source in modern manufacturing, accounting for a large percentage of plant electrical energy usage. However, the energy efficiency of such systems can be particularly low. Accurate ... -
Characterisation of an integrated telemetric temperature sensor for CFRP milling applications
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The concept of a sensor designed to measure the behaviour of a machining process is a fundamental part of process monitoring and control. The perception of such a sensor is often underestimated when novel applications are ... -
Characterisation of the performance of single point diamond dressers in abrasive processes
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)This thesis presents in-depth investigation and analysis of the dressing of conventional grinding wheels. Grinding is used in the manufacturing industry to achieve a high surface finish which is an important constituent ... -
Fundamental investigations into the micromilling of a biomedical grade polymer
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The demand for polymer micromachining has been rapidly growing for a number of years in various diverse applications. Polymer components are generally produced by moulding; however, in some instances machining may be ... -
Lean energy : a methodology to characterise and optimise energy consumption within manufacturing lines
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2015)With an ongoing increase in industrial energy demand anticipated in Europe over the next twenty years, energy efficiency continues to be an important focus within industrial environments. As consumer products have become ... -
Open Design and the Reprap Project
(2010)This paper details the investigation of an emerging trend within technology development: `open design?. Improvements in communications and computing technology have made collaboration over geographically vast distances ... -
Optimisation of process parameters and tooling during friction stir welding of AA2024-T3
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Friction stir welding (FSW) was invented and experimentally proven at The Welding Institute (TWI) in 1991. The process involves the joining of two metal pieces without melting by joining their molecules together. The tool ... -
Power and position-oriented process monitoring of freeform abrasive machining
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)Abrasive machining is used for the generation of freeform femoral implant surfaces in the biomedical industry. The abrasive machining operation is typified by high speed material removal in multiple axes, difficult-to-machine ... -
Reconfigurable test execution systems machine and process development
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)Reconfigurable manufacturing systems (RMS) are a key enabling technology to meet new challenges in a global market. These emerging products and markets are defined as having short development cycles, being highly customisable ... -
The characterisation of electrical energy consumption in complex manufacturing process chains
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The combination of increasing energy costs, corporate image concerns, and environmental legislation is driving a transition towards energy and resource efficiency within the manufacturing sector. Developing a more comprehensive ... -
The development of a surface acoustic wave strain sensor
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Multi sensors networks are becoming increasingly prevalent in modern engineering applications. In multi sensor networks, wireless sensors are preferred over traditional wired methods. Sensors based upon the surface acoustic ...
