Technology Infusion Programme (TIP) course on Micro Machining of Optical and Biomedical Parts

Date: 21 Sep 2005 - 26 Oct 2005

Venue: SIMTech, Seminar Room, Valley Block, Level 1

Course Introduction

The convenience and value of many products can be substantially increased with reduced size and weight. With the trend towards miniaturisation, micro machining becomes increasingly important in fabricating micro parts. It has found wide applications in optical engineering, bio-medical engineering, precision engineering, and MEMS systems. In this course, micro mechanical machining technologies and machining productivity will be covered.
