Abstract:
Micro-drilling (MD or D) is type of machining (processing) technology used for the drilling of miniaturized parts of small diameter in micro-scale, ie. diameter in a range of a few microns to several hundred microns. When micro-drilling metal workpieces, average micro-drilling speeds typically range between 2000 and 4000 rpm (revolutions per minute), while micro-drilling plastics use lower speeds to reduce the risk of breakage or melting. In paper is given the review of the micro-drills for drilling small holes in modern composite, smart and nano-materials. An overview of the calculation and mathematical modeling of function of cutting forces, tool wear and torque depending on the cutting regime and geometric parameters of the micro-drill when drilling small holes in different composite and nano-materials is analyzed.
