Micro components are available in a variety of shapes typically sizing from 1 mm down to 0.01 mm. Their mass production is quite common using state of the art production technology. Micro spheres for example, are on the one hand available in lot sizes up to some thousands in a constant quality within micron accuracy [1]. On the other hand they are quite commonly provided as bulk material with d...

Thanks to digital twins encompassing virtual and physical models, the cutting processes under study are attractive for improving modern manufacturing processes. The aim of this work is propose an efficient method controlling higher buckling modes a vibration micro drilling tool, which allows increase efficiency technological process.

Lubricant and coolant can improve surface roughness in machining. In addition of ecological harms, thermal shock of coolant or lubricant may affect the surface integrity especially on surface residual stresses and micro-crack nucleation. Dry machining is ecologically desirable and it is considered as a necessity for manufacturing enterprises in the recent years. 55Cr3 steel grade is steel with ...

There is a growing interest in design and manufacturing of micro-heat exchangers embedded in turbine blades of the jet engine for turbine blade cooling. The pertaining manufacturing technologies fall under micro-meso manufacturing, including subtractive methods, additive methods, and near net shaping methods. The purpose of this paper is to provide an overview of micro-meso manufacturing method...

AnECMM setup has beendesigned and fabricatedfor the purpose. Fabricated ECMM setup has different units such as mechanical machine unit, electrical power supply and control unit, electrolyt...

We show that chemical fixation enables top-down micro-machining of large periodic 3D arrays of protein-encapsulated magnetic nanoparticles (NPs) without loss of order. We machined 3D micro-cubes containing a superlattice of NPs by means of focused ion beam etching, integrated an individual micro-cube to a thin-film coplanar waveguide and measured the resonant microwave response. Our work repres...

magnetic abrasive finishing (maf) is a micromachining process that uses magnetic field and magnetic abrasive particles to conduct the mechanism of material removal in micro-nanometer scales. in this paper, by an experimental method and statistical analysis, the effects of parameters like working gap, work-piece rotational speed and material removal mechanism (injection of abrasive slurry of al2...
