has not been forthcoming and, hence, a definition of the term Micro-Machining to be implied in the context of this assessment is in order. In principle, one may take two viewpoints:(1) The first viewpoint may define Micro-Machining as the collection of all cutting operations that are performed on micro/meso-scale components and products that fall into the 100 μm to 10,000 μm size range as shown in the figure below. The Micro-Machining regime is characterized by the requirement of producing high accuracy

MOLD CASTINGS Mold casting application is a regular practice in the industry. Casting holds lubricant and enhances the mold life. The IHTC is naturally affected by the coating Alumina, fireclay, graphite are used as coatings. Hamsaid etal evaluated the influence of coating thickness and composition on IHTC which was found to be decrease by 50% as coating thickness increased by 50 to 100 micron miter. Griffith and Kawai showed that the effect of coating thickness varied of the pressure on the metal
