Short Course on Ultra-precision Machine Design and Control

Date: 20 Apr 2009 - 22 Apr 2009

Venue: Training Room 1, Tower Block, Level 3

Today’s machines - whether for semiconductor manufacturing, precision parts machining or dimensional measurements, operate with increasing precision and at faster rates. Such machines or instruments are brought about by designers having the fundamental knowledge in precision engineering and the skills in using state-of-the-art machine development tools. These experienced designers are few and much sought after. Presented by SIMTech Senior Scientists and an expert consultant, a Visiting Fellow from Cranfield University, this highly practical, results-oriented and intensive 3-day course will provide participants with basic precision engineering design principles, and latest concepts and practical solutions for achieving higher precision and accuracy in machines and products. The course includes case studies and laboratory tour.

The course topic details are as follows:

 (1) Principles of Precision Machine Design [Dr Lin Wei] This session starts with an introduction of precision engineering and the importance of precision machine design. Definitions of the key terms used in precision machine design and control are presented. The fundamentals of the precision machine design are discussed.

(2) Kinematic and Semi-kinematic Design [Mr Bill Wills-Moren] This session will outline the principles of kinematic design, discuss the benefits and limitations and introduce the concepts of semi-kinematic design and elastic averaging. The kinematic representation of real systems as part of the design process will also be covered.

(3) Precision Mechanism Design [Dr Yang Guilin] This session will focus on two types of precision mechanisms, i.e., parallel kinematic mechanism and flexure-based mechanism, which are getting popular in today’s precision machines. For each precision mechanism type, after introducing its working principles, advantages/limitations, and application examples, critical design analysis issues (such as kinetostatic analyses and general design methodologies) will be presented and illustrated.

(4) Design of Machine Structures [Mr Bill Wills-Moren] Most engineering courses cover the design of structures in a general way and concentrate on ensuring the structure will not fail. This session covers the design of structures for high precision machines and pays attention to ensuring the structure is stiff enough. The use of materials for these structures will also be covered.

(5) Computer-aided Design of Machine Structures [Dr Lin Wen Jong] This session will introduce state-of-art Computer-Aided-Engineering (CAE) with brief explanation and examples on the usage of CAE tools for the design of machine structure.

(6) Guideway Design [Mr Lim Chee Wang]
Motion performance and ease of control is greatly influenced by the guideway characteristics. This session will introduce the common types of guideways used in ultra-precision machine, as well as their performances, applications and practical issues to consider when using them.

(7) Sensors and actuators for precision machines [ Daniel Teo] This session focuses on the principle of the measurement systems used in modern precision machines, which include the linear, rotary, and angular encoders for long range applications and the ultra-precision sensors for short-range measurement. In addition, the principle and applications of linear motors, electromagnetic actuators, piezoelectric actuators and other ultra-precision actuators will also be presented and discussed.

(8) Precision Motion Control [Dr Gong Zhiming] From system perspectives, this session will cover various devices and components which form a complete motion control system. Topics of this session Include linear motors and their drivers, measurement and feedback, industrial motion controllers, system performance, PID tuning, feedback and feedforward control, command profiling, etc.

(9) Metrology Instruments [Dr Fang Zhongping] This session will introduce the principle and application of laser interferometry technology for precision machine metrology. The fundamentals of both laser displacement measurement interferometer and laser tracker will be discussed.

(10) Machine Calibration and Error compensation [Dr. Teo Chek Sing] The “What”, “Why”, “How” of machine calibration will be answered in this session. The calibration methods are discussed under three headings – Parametric, Artifact and Global techniques. A case study using global technique will be used to illustrate the sequences in calibrating an Anorad XY-motion machine from the selection of the calibration tools to the implementation of an error compensation map to the final machine assessment.

 (11) Thermal Effects [Dr Lin Wei]
This session starts with the background of thermal effects for precision machine design and then introduces the measurement tools and control method to investigate and isolate the thermal effects on the machine. Examples will be presented and discussed

(12) Error Budgeting [Mr Bill Wills-Moren] Cranfield Precision Ltd (and prior to that Cranfield Unit for Precision Engineering) have developed and used error budgeting techniques to estimate the errors in machines they are designing for many years. This session outlines these principles in simple terms and gives some examples.

(13) Design Case Studies [Dr Lin Wei and Mr Bill Wills-Moren] Cases include design of a decoupled stage, Koda machine, Big BOX grinding machine
