Overview of Micro-Manufacturing

There is a growing demand for industrial products not only with increased number of functions but also of reduced dimensions. Micro-machining is an emerging technology for the production of such miniaturized parts and components. In this present trend, new fabrication methods for producing miniaturized components are gaining popularity due to the recent advancements in micro electro mechanical systems (MEMS). Micro manufacturing include both conventional and nonconventional material removal process. The conventional machining process like micro-drilling, micro-milling etc. are used in fabricating micro components. The non-conventional process includes etching, various lithographic techniques like LIGA and laser micro machining etc. This literature report focuses on the recent trends in micro machining processes, process parameters and its quality characteristics.
