Efficiency and Sustainability of Mechanical Micromachining
Sirikienthong, Sirichai (epxss18@nottingham.ac.uk)
School of Mechanical, Materials and Manufacturing Engineering, M3 Synopsis: Nowadays, the advancement of technological innovation has greatly driven the size of components of high technology products down. The more complex mechanism inside those products requires the combinations of smaller components. The manufacturers of those components are needed to be responsive to the demand. Furthermore, they also have to be sustainable because the climate change has been a global issue. Therefore, they have to improve and adapt their process to maintain the competitiveness. Mechanical Micromachining includes micro milling, micro turning, micro cutting and micro drilling are the new continuously improving technology which could be more suitable to produce micro components in both terms of efficiency and sustainability as Mukhopadhyay (2010) mentioned. Moreover, in some cases, mechanical micromachining is even more precise and flexible than conventional CNC machines. In this study, the performance of mechanical micromachining, conventional machining, electrical discharge machining (EDM) and non-conventional micromachining are compared in three ways: potential and efficiency, sustainability, and limitations. The further development is also provided in this study.
Introduction
Increasing intensity of competition in global markets makes manufacturing firms attempt to raise their production performance, i.e. increase their production rate while unnecessary costs of production is reduced. One efficient way to do so is to employ new technologies for the production processes, which would benefits the firms in selecting the most suitable technique for their manufacturing process. According to Colton (2009), there are 5 micromachining techniques which are photolithography, etching, lithography, electroplating, and molding
