Current activities

Dr Tan Jin is a highly experienced researcher with expertise in micro machining, ultra precision and high performance machining. He has over 15 years of experience in research and teaching, including working in industry and collaboration with industrial partners. His knowledge embraces wide areas including the modelling of complex thermal, fluidic and mechanical phenomena to aid product design and process optimisation, development of precision, ultra-precision and high performance machining processes, process monitoring and control, allied to experience of project management. He has published approximately 50 high quality scientific and technical papers, many of which are in highly regarded international journals. He received the prestigious IMEchE Joseph Whitworth Award and also the PE Publishing Award for the best paper published in the Proceedings of the Institution of Mechanical Engineers, Part B, Journal of Engineering Manufacture, in 2006.

His recent research interests include the development of micro milling process using very small cutting tools with tip diameters down to 50 mm. This involves the simulation of the micro milling process using FE micro cutting software and the analytical micro milling force modelling with detailed consideration of tool geometry, local material removal and contact conditions. The machining of complex 3D micro shapes are aided by a special CAD/CAM tool which supports the micro milling functions and helps to produce the optimal tool paths and CNC programmes for making the components on a 5-axis high precision milling centre. To enhance the micro fluidic device design, analysis and CFD modelling of the two phase micro fluidic flow also have been carried out.

Dr Tan Jin provides lectures to postgraduate programme students as well as supervising MSc and PhD students. This work covers different topics including material engineering, process development, thermal modelling, web-based databases and visual instrumentation for process monitoring and control.

Background

Dr Tan Jin’s research dates back to the period when he was working as associate professor and lecturer in Liaoning Institute of Technology, China. He developed a research activity centred on abrasive machining process, design of machine tools, moulds and fixtures, high speed grinding and machining process control. He has been educated in China and obtained his PhD, based on modelling the high efficiency deep grinding process, from the Northeastern University, Shenyang. He has also spent one year in Germany studying high speed grinding technology at the University Kaiserslautern.
