Professor Andrew Torrance

Fellow Emeritus (Mechanical, Manuf & Biomedical Eng)


Prof. Andrew Torrance graduated from Cambridge in 1968, then went to the lubrication group at Imperial College, London where he obtained a Ph.D. in 1971. After a year as a Research Assistant he moved to the laboratories of Total in Harfleur, France where he spent 2" years as Chef de Section frottement - usure. Returning to England, he spent 5 years as a Research Fellow in the Abrasive Machining Group at the University of Bristol before joining the teaching staff at Trinity College, Dublin in 1980, where he is now an Associate Professor and Fellow of the College. His main research interests are in abrasive machining, and the modelling of boundary friction and wear, and he is the author of some 70 papers on these subjects.

1. MIST-JET COOLING OF GRINDING: This project, sponsored by Enterprise Ireland, is to prove the concept of mist jet cooling for abrasive machining. A prototype cooler has been built, and is available for demonstration on site.It can be extremely effective with very small quantities of environmentally friendly liquids. 2. MEASUREMENT OF ABRASIVES AND ABRASIVE TOOLS: This project, sponsored by the Irish Council for Science, Engineering and Technology, seeks to develop a method for accurately quantifying the sharpness of individual abrasives, and of abrasive tools using stereo microscopy. 3. ENHANCED GAS-JET COOLING OF MACHINING PROCESSES: This project, sponsored by Science Foundation Ireland, seeks to apply the techniques developed in the project on grinding to other machining processes. Early results indicate that excellent results are possible with environmentally friendly fluids and good nozzle design. 4. ENHANCED GAS-JET COOLING OF DISK BRAKES: This project, sponsored by Science Foundation Ireland, seeks to apply the techniques developed in the projects on grinding and machining to the cooling of disk brakes. Preliminary work is ongoing on the design of a suitable process. 5. FUEL AND LUBRICANT INTERACTIONS WITH NON-FERROUS METALS: This project, sponsored by the E.U.and Shell Global Solutions seeks to investigate the effects of fuel and lubricant additives on the froistion and wear of contacts involvoing non-ferrous metals. The outcome of the project will be a fuller understanding of the formation of surface films on surfaces other than steel, and how the surface film contributes to the friction and wear performance of the lubricant in such systems. 6. A NEW TEST FOR FRICTION IN FORGING: This is an unsponsored research project to develop a new, test more realistic than the conventional ring test to measure friction in forging.
