Micro level machining of metals is a direct operation to manufacture miniature parts. The current article a comprehensive review on micro machining has been carried out for metal cutting process. The key role in manufacturing of parties is good understanding of mechanic behavior of given material. Material removal mechanism of micro machining and conventional machining have significant differences due to the scaling effects associated with tool-geometry, tool material and work piece material characteristics. To explore the significance of range of cutting parameters on cutting force, surface roughness, temperature, tool life, vibration and tool wear, machining tests were conducted in literature. As a result, micro machining is a developing field which has shown to be a prospective approach to produce features on the parts in the range of a few to a few hundred microns with acceptable machining quality.
