Laser micromachining has great potential as a MEMS (micro-electro-mechanical systems) fabrication technique because of its materials flexibility and 3D capabilities. The machining of deep polymer structures with complex, well-defined surface profiles is particularly relevant to microfluidics and micro-optics, and in this paper we review recent work on the use of projection ablation methods to f...

Micro-rod YAG single crystals are the preferred laser for gain mediums with a high power. However, brittle fracture and crack damages easy to occur in grinding process of micro-rod due their large length-to-diameter ratio, brittleness, hardness. In this work, modal, frequency, harmonic response transducer under ultrasonic elliptical vibration analyzed by using finite element simulation. Then, m...

Abstract As compared to traditional milling, ultrasonic-assisted cutting of honeycomb core materials has the advantages small force and superior surface quality. Currently, ultrasonic straight blade V-shaped machining is one most efficient roughing processes. The requirement a processing path be post-processed based on characteristics cutter key issues faced while meeting technological requirem...
