“…Using this model, they revealed the formation mechanism of crater defects on metal materials machined using microsecond laser pulses. They also employed laser micro-milling to machine ceramics and silicon nitride micro-components [85]. These previous works verify the machining accuracy of laser micro-milling at the micrometric scale.…”

Device miniaturization is an emerging advanced technology in the 21st century. The miniaturization of devices in different fields requires production of micro-and nano-scale components. The features of these components range from the sub-micron to a few hundred microns with high tolerance to many engineering materials. These fields mainly include optics, electronics, medicine, bio-technology, communications, and avionics. This paper reviewed the recent advances in micro-and nano-machining technologies, including micro-cutting, micro-electrical-discharge machining, laser micro-machining, and focused ion beam machining. The four machining technologies were also compared in terms of machining efficiency, workpiece materials being machined, minimum feature size, maximum aspect ratio, and surface finish.

“…The removal of material during laser milling is affected by the characteristics of the laser beam and the workpiece but is mainly determined by the way that both interact [4]. The key process parameters which can be controlled and modified in order to obtain optimal machining results are the pulse frequency, the pulse intensity, and the scanning speed.…”

This paper presents a multi-objective optimization of the laser milling process of micro-cavities for the manufacturing of drug eluting stents (DES). The diameter, depth and volume error are considered to be optimized in function of the process parameters including laser intensity, pulse frequency and scanning speed. A set of designed experiments is carried out in a pulsed Nd:YAG laser system using 316L Stainless Steel as a work material. Two different geometries are studied, and they are considered as another variable for the model. The multi-objective optimization problem is solved by NSGA-II algorithm, and the non-dominated Pareto-optimal fronts are obtained. The capability of the process to manufacture within a level of error is also investigated. Relative error capability maps for different scale of features are presented.
