“…The industrial sector, including chemical, aerospace, medical, microelectronics and automotive, has e become the main user of miniature finished products with high quality, high precision and high 3D accuracy [ 1 , 2 , 3 , 4 , 5 ]. While processes such as electro-discharge machining, laser micro manufacturing, lithography, and deep reactive ion etching can be used for micro components, these are not cost effective, and require highly skilled manpower and high operation time [ 6 , 7 , 8 , 9 , 10 ]. Micro milling is the most popular micro-machining process, as it is time and cost effective for the production of 3D miniature parts.…”

Super alloys offer excellent mechanical and chemical properties at elevated temperatures that make them an attractive choice for aerospace, automotive and chemical processing, and marine applications. These alloys are, however, difficult to machine due to their high strength at elevated temperatures, low thermal conductivity and work hardening. In this study, micro milling of Inconel 600 super alloy has been carried out and the effects of the key input parameters (cutting speed, feed rate, depth of cut) on response parameters (burr formation, surface roughness and tool wear), under various cooling conditions (dry, wet and cryogenic), have been analyzed. High speed micro milling (range up to 80,000 RPM) was carried out, while keeping the feed rate values below and above the cutting edge radius. The Taguchi design of experiments was used during this study. The results have been analyzed using SEM and 3D optical microscopy. Analysis of Variance (ANOVA) revealed that the best surface roughness values can be achieved under cryogenic machining condition with an overall contribution ratio of 28.69%. It was also revealed that cryogenic cooling resulted in the highest tool life with the contribution ratio of cooling conditions at 26.52%.

“…Miniaturised components can be manufactured by (i) electro-discharge machining [7][8][9][10], (ii) laser micromanufacturing [11][12][13], (iii) lithography, electroplating and moulding (LIGA) [14,15], (iv) deep reactive ion etching [16,17], (v) deep UV lithography [18,19] or (vi) mechanical micromachining [20][21][22][23][24] technologies. Excellently precise geometrical features and small tolerances can be achieved by these micromachining technologies; however, their operation time and cost are often extremely high.…”

Recently, mechanical micro-milling is one of the most promising micro-manufacturing processes for productive and accurate complex-feature generation in various materials including metals, ceramics, polymers and composites. The micro-milling technology is widely adapted already in many high-tech industrial sectors; however, its reliability and predictability require further developments. In this paper, micro-milling related recent results and developments are reviewed and discussed including micro-chip removal and micro-burr formation mechanisms, cutting forces, cutting temperature, vibrations, surface roughness, cutting fluids, workpiece materials, process monitoring, micro-tools and coatings, and process-modelling. Finally, possible future trends and research directions are highlighted in the micro-milling and micro-machining areas.
