报告题目：Hybrid micromachining - a paradigm shift in micromanufacturing
报告人简介：Xichun Luo is a Professor in ultra precision manufacturing and technical director of Centre for Precision Manufacturing (CPM) at the University of Strathclyde (Glasgow). He is a Fellow of the International Society for Nanomanufacturing and an editor for Proceeding of IMechE Part C: Journal of Mechanical Engineering Science, Journal of Micromanufacturing, Advances in Mechanical Engineering and Mechanical Sciences. He also sits in the editorial board for Micromachines, Nanomanufacturing and Metrology. He obtained his PhD in ultra precision manufacturing at Harbin Institute of Technology (China) and second PhD in Precision Engineering at Leeds Metropolitan University (UK). From 2004 to 2007, he worked at Cranfield University as a research officer to develop freeform diamond turning/ grinding process and machines. From 2007 to 2012 he was a lecturer at Heriot-Watt University and established Nanomanufacturing Laboratory. From 2012 to 2013 he was a Reader in ultra precision manufacturing at the University of Huddersfield where he leads an Advanced Machining Research Group. His research has been founded by the EPSRC, EC, Royal Society and Industry. His research interests include ultra precision machining brittle materials, freeform machining, precision motion control, hybrid micromachining and FIB nanomanufacturing, as evidenced by two books and more than 100 papers in peer-reviewed highly ranked journals. He chaired two IEEE International Conferences in Automation and Computing in 2014 and 2015. He won UK Institution of Mechanical Engineers (IMechE) 2015 Ludwig Mond Prize for his work in the application of digital technology in micro- and nano-manufacturing.
报告内容：Micromanufacturing has attracted great attention as micro-components/products such as micro-displays, micro-sensors, micro-batteries, etc. are becoming established in all major areas of our daily life and can already been found across the broad spectrum of application areas especially in sectors such as automotive, aerospace, photonics, renewable energy and medical instruments. These micro-components/products are usually made of multi-materials (may include hard-to-machine materials) and possess complex shaped micro-structures but demand sub-micron machining accuracy. A number of micro-machining processes is therefore, needed to deliver such components/products.
The talk introduces the concept of hybrid micro-machining process which involves integration of various micro-machining processes with the purpose of improving machinability, geometrical accuracy, tool life, surface integrity, machining rate and reducing the process forces. It uses three typical hybrid micromachining processes to demonstrate the effectiveness of hybrid micromachining process in terms of machining performance and productivity. Development a new 6-axis hybrid micro machine tool and material handling system to implement the hybrid micromachining processes is also introduced. The talk concludes with the future research focus and challenges of hybrid micromachining in the new era of smart manufacturing.
