Micromachining is the most basic technology for the production of miniaturized parts and components. Micro turning is one type of micromachining process which uses a solid tool and its material removal process is almost similar to conventional turning operation. The objective of this paper is to provide a state of the art in the field of micro turning. In recent years, researchers have explored a number of ways to improve the micro turning process performance by analyzing the different factors that affect the quality characteristics. The experimental and theoretical studies show that the process performance can be improved considerably by proper selection of micro turning parameters. This paper reviews the research work carried out so far in the area of micro turning and reports about the experimental and theoretical studies on micro turning to achieve more efficient material removal rate coupled with reduction in tool wear and improved surface quality.
