Ultra-Precision Machine Design and Control

Date: 12 Feb 2004 - 13 Feb 2004

Venue: Training Room 2, TOWER Block, SIMTech Tower Block, 71 Nanyang Drive

Course Outline :

The demand for ultra-precision machines (UPM) is increasing. As the needs for miniaturization and high-density components increases, the applications of the UPM are no longer limited to the machine tools, but also expand into other applications such as inspection, pick-and-place, and measurements and lithography. However, development of the UPM capable of achieving high performance in terms of both static and dynamic specifications is much more challenging than that of the conventional machinery. This course therefore aims to provide a comprehensive understanding on how the UPMs are designed and developed. The principles and practices of high precision machine design will be addressed. The practical issues and techniques in precision machine calibration, linear motor control, and machine vibration will be discussed and demonstrated.

Topics includes

1.  Principles and techniques of precision machine design (LW & LYP)
2.  Error budgeting (LYP)
3.  Structure and mechanisms (LW)
4.  Kinematic design (LW)
5.  Air bearings applications (LYP)
6.  Material selection (LYP)
7.  Calibration and instrumentation (LHC)
8.  Error compensation (LHC)
9.  Motion control strategies (LHC)
10. Dynamic analysis of structure (LHZ)
11. Vibration control (LHZ)

Course Leaders :

Dr. Lin Wei obtained his B.Sc. from University College London, UK in 1985, his M.Sc. and Ph.D. from University of Florida, USA, in 1988 and 1992, respectively. All his degrees are in Mechanical Engineering. Since 1992, he has been with Singapore Institute of Manufacturing Engineering and responsible for the development and implementation of many industrial mechatronic systems, including a petent pending high-precision X-Y stage. He is now a Senior Scientist and the Manager of Mechatronics Group. Dr. Lin's current research interests include ultra-precision motion system, parallel mechanisms, and photonic packaging automation.

Liaw Hwee Choo received B.Eng degree (First Class Honours) in Electrical Engineering and M.Eng degree from Nanyang Technological University (NTU) in 1992 and 1997 respectively. He worked as a product engineer at International Video Products, Singapore, in 1992 and 1993. From 1993 to 1995, he was a research/teaching assistant with NTU performing research in field of robotic control. From 1995 to 1998, he worked for CET Technologies Pte Ltd., Singapore. During his stay in CET, he was assigned to DSO National Laboratories to develop control electronics for position-tracking systems. Since the end of 1998, he has been with Singapore Institute of Manufacturing Technology. Currently, he is working as a Senior Research Engineer and his research interests are in the areas of high-precision motion control, robotic applications, and industrial automation.

Dr. Li Huaizhong obtained his B.Eng. from Tsinghua University, China in 1988, his M.Eng. from Xi’an Jiaotong University, China in 1991, and his Ph.D. from the National University of Singapore in 2002, all in Mechanical Engineering. He has long term experience in vibration testing and control, sensing and signal processing, as well as condition monitoring and fault diagnosis. Dr. Li is now a Senior Research Engineer at Singapore Institute of Manufacturing Technology. His research interests include experimental modal analysis, vibration measurement and control, advanced manufacturing technology, and high precision motion system.

Mr. Leow Yong Peng obtained both his Degree of Bachelor of Engineering (B.Eng) and Degree of Master of Engineering (M.Eng) in the field of Mechanical Engineering from The Nanyang Technological University of Singapore in 1996 and 2002, respectively. From 1996 till 1998 he worked as a Senior Design Engineer in IC Equipment Pte Ltd where he is involved in the design and development of prototypes for the semiconductor industrial. In SIMTech, he is involved in the design, development and manufacturing of high precision equipment especially in the area of high precision positioning, as well as flexural-base mechanisms.

About TIP
