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.

• Title

  Software for the prediction of friction coefficients.
  Summary

  Renault commissioned this work to develop a friction model and software to allow for the conditions in the contact between a piston ring and cylinder liner. By allowing for both elastic and plastic deformation of asperities, and for the properties of boundary films, it could be shown that there is an optimum finish for these components. If the finish is either too rough or too smooth, there is a danger of high friction and scuffing. The models developed predicted well the friction measured experimentally for a wide range of finishes. Software to implement the algorithms can be found at: www.mecheng.tcd.ie/~torrance/software.html
