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...

A hybrid-hybrid (ultrasonic-assisted + laser-assisted) turning study of silicon carbide reinforced aluminium metal matrix composite is presented. The results show a significant reduction average cutting force with an improved surface finish machined components compared to conventional machining, implying that this new and novel paradigm viable machining process.

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 ...

In this study, an ultrasonic-assisted electrochemical grinding (UAECG) system was designed to improve the low efficiency and tool wear in conventional of hard tough materials. system, multiple-field energy consisting ultrasonic, mechanical used. The processing mechanism investigated determine interaction between processing. established theoretical model showed that affected by ultrasonic amplit...

In this paper, a micro ultrasonic motor using a micro-machined bulk piezoelectric transducer is introduced. The cylindrical shaped bulk piezoe t U e ©

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...
